                                                            File No. 333-259570

       Dear Mr. Farrell:

             We have reviewed your amended registration statement and have the
following
       comments. In some of our comments, we may ask you to provide us with
information so we
       may better understand your disclosure.

              Please respond to this letter by amending your registration
statement and providing the
       requested information. If you do not believe our comments apply to your
facts and
       circumstances or do not believe an amendment is appropriate, please tell

       Form S-4

       Background of the Business Combination, page 126

   1.                                                   We note your response
to comment 4 and the statement on page 128 that the parties
                                                        agreed that the 85%
split for covered future tax benefits was reasonable and customary
                                                        when compared to
similarly situated companies with UP-C structures. Please reconcile
                                                        with the statement on
page 14 that UP-C structures are not used in initial business
                                                        combinations with
SPACs. It is unclear to what extent the negotiations of the UP-C
                                                        structure's benefits
and potential benefits to the Flow Through Sellers involved concerns
                                                        from the perspective of
Thayer. Please revise accordingly.

2.       It appears the BDO opinion on what the tax consequences "should" be is
subject to
         uncertainty. Please revise the disclosure and opinion to clarify
whether it is subject to
         uncertainty and, if so, explain why BDO cannot give a    will
opinion, and describe the
         degree of uncertainty in the opinion. Include risk factor and/or other
appropriate
         disclosure setting forth the risks of uncertain tax treatment to
investors. The opinion may
         also state which position the registrant intends to take if challenged
by the IRS. For
         reference, see Section III.3.C.4 of Staff Legal Bulletin No. 19.
Please also include an
         appropriate consent.

3.       We note your revised disclosure and response to comment 10 and reissue
the comment.
         You distinguish between the serviceable and addressable markets by
stating that the
         higher TAM figures would require changes to the business model.
However, it is unclear
         how the examples provided on page 217 (further investments in the
business and
         operations, and capturing high net worth households even though the
"lodging spend by
         high net worth individuals engaged in luxury travel" already appears
to be captured by the
         serviceable market) would require changes to the business model. What
is the basis for
         the significantly larger addressable market, and why is that market
appropriate when it
         covers total room revenues of luxury hotel chains and luxury private
rentals, and
         Inspirato's planned innovation for luxury hospitality suppliers would
only monetize part of
         their inventory "that would otherwise spoil"? Please revise to clarify
the reasoning and
         assumptions so that the disclosure of Inspirato's projected market is
understandable to the
         average investor.

4.       We note your response to comment 12. Please revise the description of
your ARR key
         metric on page 241 to clearly explain the difference, if any, between
annual subscription
         revenue (defined as "the product of the annual subscription cost
multiplied by the number
         of subscribers") and ARR (defined as "the number of Active
Subscriptions as of the end of
         a period multiplied by the then-current annualized subscription
rate").
