       Prospectus Summary, page 27

   1.                                                   Please clarify if the
sponsor and its affiliates can earn a positive rate of return on their
                                                        investment, even if
other SPAC shareholders experience a negative rate of return in the
                                                        post-business
combination company.
   2.                                                   Please revise the last
Question and Answer on page 11 and where appropriate to address
                                                        the PIPE financing
closing condition. It appears the condition cannot be waived, and the
                                                        opportunity should be
provided to vote separately on the issuance of shares in connection
                                                        with the merger and the
PIPE financing.
   3.                                                   Regarding the PIPE
transaction disclosure on page 31, please highlight material
                                                        differences in the
terms and price of securities issued at the time of the IPO as compared

         to private placements contemplated at the time of the business
combination. Disclose if
         the SPAC   s sponsors, directors, officers or their affiliates will
participate in the private
         placement.
4.       We note your disclosure titled Interests of Thayer's Directors,
Officers, and Others in the
         Business Combination on pages 31 and 32. Please highlight the risk
that the sponsor will
         benefit from the completion of a business combination and may be
incentivized to
         complete an acquisition of a less favorable target company or on terms
less favorable to
         shareholders rather than liquidate.
5.       Please revise the conflicts of interest discussion at the summary
level contained under the
         heading Interests of Thayer's Directors, Officers, and Others in the
Business
         Combination on pages 31 and 32 so that it highlights all material
interests in the
         transaction held by the sponsor and the company   s officers and
directors. This could
         include fiduciary or contractual obligations to other entities as well
as any interest in, or
         affiliation with, the target company, or whether the directors or
sponsor were required to
         vote in favor of a presented initial business combination. In
addition, please clarify how
         the board considered those conflicts in negotiating and recommending
the business
         combination.
6.       Please expand your conflicts of interests disclosure on pages 31 and
32 to include whether
         the sponsor has any ownership interest in the target company. Should
the sponsor have an
         ownership interest in the target company, disclose the approximate
dollar value of the
         interest based on the transaction value and recent trading prices as
compared to the price
         paid.
7.       We note that the sponsor has agreed to waive its redemption rights.
Please describe any
         consideration provided in exchange for this agreement.
8.       Revise your disclosure on page 39 that illustrates the potential
impact of redemptions on
         the per share value of the shares owned by non-redeeming shareholders
by including a
         sensitivity analysis showing a range of redemption scenarios that not
only includes
         minimum and maximum redemption levels, but also interim redemption
levels.
9.       We note the statement on page 99 that the parties agreed to the UP-C
organizational
         structure for tax and other business purposes. Please revise to
clearly explain in terms
         understandable to the average investor what the tax and business
purposes are and the
         extent to which the structure is unusual compared to other mergers and
initial business
         combinations by SPACs. Additionally, we note the statement on page 150
that PubCo
         will be required to make payments under the TRA. Please clarify why
such payments do
         not "give rise to any significant business or strategic benefit or
detriment."
10.      With respect to the UP-C structure, please identify the Flow-Through
Sellers and disclose,
         if material, any economic differences or potential economic
differences between the Class
         A common stock held by the public and interests held by the
Flow-Through Sellers and
         others. Please clearly explain any such differences and risks they
pose to public

Risk Factors, page 49

11.      We note your disclosure of the risk of dilution of the value of
shareholders shares in the
         combined company on pages 80, 86 and 95. Please revise to disclose all
possible sources
         of dilution and the extent of dilution that shareholders who elect not
to redeem their shares
         may experience in connection with the business combination. Provide
disclosure of the
         impact of each significant source of dilution, including the amount of
equity held by
         founders, convertible securities, including warrants retained by
redeeming shareholders, at
         each of the redemption levels detailed in your sensitivity analysis,
including any needed
         assumptions.
12.      We note your disclosure on page 88 concerning the material risks to
unaffiliated investors
         presented by taking the company public through a merger rather than an
underwritten
         offering. Please revise your disclosure to include not only the risk
presented by the
         absence of due diligence conducted by an underwriter, but also that
such an underwriter
         would be subject to liability for any material misstatements or
omissions in a registration
         statement.
Unaudited Pro Forma Condensed Combined Financial Information
Note 4. Net loss per share, page 109

13.      Please tell us how you calculated pro forma basic and diluted loss per
share, assuming no
         redemption and assuming maximum redemption, for all periods shown.
Based upon the
         amounts on the schedule on page 110, it appears that pro forma net
loss for the year ended
         December 31, 2020 should be $0.05.
Background of the Business Combination, page 120

14.      Please expand your background discussion to provide more detailed
disclosure regarding
         key negotiation considerations and how they changed over time.
Currently the
         background disclosure references negotiation topics without providing
details or
         explaining their significance or how they may have changed before
being reflected in the
         proposed initial business combination. As examples only, please
further explain the key
         terms and negotiated items involving "a proposal for a business
combination" on page
         121; "transaction structure and exchange rights," "historical and
projected financial
         performance," "investor presentation that would be shared as part of
the PIPE" on page
         122; and "a further updated non-binding letter of intent" and
"projected financial
         performance" on page 123. Please identify the original terms as well
as how and why any
         terms were revised over time. Please also provide a more detailed
description of
         any indications of interest or letters of intent and confidentiality
agreements entered into
         with the 50 other potential targets and identify the potential target
companies that received
         formal indications of interest and/or draft letters of intent.
15.      Please also expand your disclosure of the key terms to clarify how
they were negotiated

         and ultimately resulted in the proposed transaction. As non-exclusive
examples, it is
         unclear why you do not address the five-person board of managers, the
Class V common
         shares or the PIPE investment, and the UP-C structure in more detail,
including which
         parties proposed them and the extent to which the terms evolved during
negotiations.
         Please also explain how the value resulted in $1.07 billion when the
parties had discussed
         $1.25 billion and other values.
Proposals to be Considered by Thayer's Stockholders, page 120

16.      We note your disclosure on page 120 concerning your hiring of a
financial advisor,
         Evercore, and the lack of a obtaining a fairness opinion from them in
connection with the
         business combination on page 126. Please revise your disclosure to
include the level of
         diligence performed by your financial advisor, including any material
data or analyses
         provided to you by your financial advisor. Additionally, please
disclose the basis for the
         board's decision not to seek a fairness opinion from your financial
advisor with regards to
         the business combination.
17.      We note your disclosure on page 122 discussing the PIPE transaction,
specifically, that
         both parties, Inspirato and Thayer, worked on an investor presentation
that would be
         shared as part of the PIPE transaction. Please disclose whether
investor presentation
         materials provided as part of the PIPE are materially consistent with
the information
         contained within this filing.
Certain Inspirato Projected Financial Information, page 127

18.      Please revise to expand and further clarify in quantitative and
qualitative terms the
         "number of assumptions" beginning at the bottom of page 128. For
example, it is unclear
         whether and on what basis the projections assume accelerating
subscription rates or the
         addition of new subscribers in excess of existing subscribers net of
cancellations. It is
         also unclear what amounts of "investments in sales and marketing" and
other items
         underlie the projections. Similarly, it is unclear what amounts of
"further penetrat[ion] of
         existing subscriber base" are assumed, and what amounts of cash "made
available from
         the Trust Account" are assumed. Please revise accordingly.
19.      In this regard, we note your financial projections cover 5 years.
Please explain the basis
         for presenting forecasts extending five years.
20.      We note the statements on page 127 that readers are "cautioned not to
rely on the
         projections" and that the projections "should not be looked upon as
'guidance' of any
         sort." Please revise to remove the statement suggesting investors
cannot rely on the
         disclosures; and reconcile the characterization of the projections not
being "guidance"
         with the disclosures elsewhere that Thayer and the Thayer board of
directors considered
         Inspirato's outlook in deciding to recommend the initial business
combination. It is
         unclear how the projections, estimates and outlooks were not
understood as guiding the
         company's and the board of directors' decision making.

21.      We note from page 123 and elsewhere in the Background of the Business
Combination
         that the parties discussed projections at multiple stages of the
negotiations. It is unclear if
         Inspirato modified the projections over time. Please clarify the
extent to which multiple
         sets of projections exist.
Projections, page 128

22.      We note that the Inspirato revenue projections assume revenue growth
that far exceeds
         growth for the historical periods presented in the filing. Please
revise your filing to
         provide more detailed disclosure of your revenue growth assumptions
and the reasons you
         believe these assumptions are reasonable.
Material U.S. Federal Income Tax Considerations of the Redemptions, page 153

23.      We note statements on page 155, including treatment of redemptions
under U.S. federal
         income tax regulations. We also note that the Business Combination
Agreement seeks
         treatment under Section 368(a) for aspects of the transaction. Please
amend the disclosure
         here, and where appropriate, to describe the federal income tax
consequences of the entire
         transaction, including the merger, and not just the federal income tax
consequences of
         redemptions. If the merger will result in tax consequences to U.S.
shareholders that are
         material, please file a tax opinion as an exhibit to the registration
statement.
Information about Inspirato, page 188

24.      We note the statement on page 187 regarding branded private luxury
"homes available
         exclusively" to Inspirato subscribers. Please revise to identify the
exclusive brands.
25.      We note the disclosure switches back and forth between TAM and SAM.
Please revise to
         clarify when and why you cite these data sets. In this regard, it is
unclear why $230
         billion would be the appropriate demand for Inspirato's services when
TAM appears to
         assume a significant portion of the market is and will be provided by
the "hospitality
         suppliers" separate from Inspirato subscribers or revenue.
26.      We note the statement on page 192 that branded private luxury vacation
residences "make
         up the heart of the Inspirato portfolio." As the number of residences
and resort partners
         reflect a higher number of hotel and resort partners, revise here and
in the MD&A
         section to clarify why the branded private luxury vacation residences
make up the heart of
         the portfolio.
Certain Inspirato Relationships and Related Party Transactions, page 220

27.      Please revise to identify the parties to the transactions. As
non-exclusive examples, you
         reference "certain members of Inspirato's board of managers,"
"entities affiliated with
         Brad Handler," "an entity affiliated with W Capital Partners III," and
"certain other key
         employees." Please also identify the material terms of the several
agreements under the
         Series E Preferred Unit Financing and quantify the reserve requirement
of the Guarantee

28.      We note the discussion of ARR on page 226 and the comparison against
ARR for Netflix,
         Wheels Up and others in Exhibit 99.2. Please clarify the extent to
which your calculation
         of ARR differs from those of your competitors and the companies you
cite. We also note
         the statement on page 226 that active contracts at the date used in
calculating ARR may or
         may not be extended by subscribers. Please clarify the extent to which
you have
         experienced periods when your ARR did not capture recurring revenue by
material
         amounts.
29.      Please revise to identify the parties and circumstances involved in
the $9 million of debt
         forgiveness in 2021.
30.      We note the statement on page 231 that Inspirato's agreements are
typically monthly or
         annual. Please revise to quantify the approximate percentages of
monthly and annual
         contracts, and clarify if material the extent to which margins and
retention rates differ.
         Please also clarify the extent to which margins are materially
different between travel and
         subscription revenues.
31.      Please advise us why the revolving line of credit and credit
facilities identified on page
         236 are not filed as material agreements under Item 601(b)(10) of
Regulation S-K.

Cash Flow so
         that it follows the discussion of GAAP operating results. Refer to

33.      We note your repeated disclosures throughout the filing that Thayer's
directors and
         officers will not be reimbursed for out of pocket expenses incurred in
pursuit of the initial
         business combination. Please reconcile such statements with the
statements made on page
         245 that provide that the sponsor as well as directors and officers of
Thayer will be
         reimbursed for out of pocket expenses in pursuit of an initial
business combination.

34.      We note the statement that no charges were incurred as of December 31,
