                           Registration Statement on Form S-3

Ladies and Gentlemen:

                  We have acted as special counsel to Starwood Hotels & Resorts
Worldwide, Inc., a Maryland corporation (the "Corporation"), and Starwood Hotels
& Resorts, a Maryland real estate investment trust (together with the
Corporation, the "Company"), in connection with the preparation of the
Registration Statement on Form S-3 of the Company and the other registrants
named therein, initially filed on or about the date hereof (as thereafter
amended from time to time and together with all exhibits thereto, the
"Registration Statement"), which also constitutes a post-effective amendment to
each of the Company's Registration Statements on Form S-3 initially filed on
November 17, 1997 (Registration Nos. 333-40077 and 333-40077-1), October 3, 1996
(Nos. 333-13411 and 333-13411-01) and November 16, 1995 (Nos. 33-64355 and
33-64355-01), respectively. This opinion is being furnished in accordance with
the requirements of Item 16 of Form S-3 and Item 601(b)(8) of Regulation S-K
under the Securities Act of 1933, as amended (the "Act"). Capitalized terms used
but not otherwise defined herein have the respective meanings set forth in the
Registration Statement.

                  Our opinion is based upon an examination of the Registration
Statement and such other documents as we have deemed necessary or appropriate as
a basis therefor. In our examination, we have assumed the legal capacity of all
natural persons, the genuineness of all

signatures, the authenticity of all documents submitted to us as originals, the
conformity to original documents of all documents submitted to us as certified,
conformed, or photostatic copies, and the authenticity of the originals of such
copies.

                  In rendering our opinion, we have considered the applicable
provisions of the Internal Revenue Code of 1986, as amended, Treasury
Regulations, judicial decisions, administrative rulings and other applicable
authorities, in each case as in effect on the date hereof. The statutory
provisions, regulations, decisions, rulings and other authorities on which this
opinion is based are subject to change, and such changes could apply
retroactively.

                  This opinion letter shall not be construed as or deemed to be
a guaranty or insuring agreement. Opinions of counsel represent only counsel's
best legal judgment and are not binding on the IRS or on any court. Accordingly,
no assurance can be given that the IRS will not challenge the propriety of the
opinion set forth herein or that such a challenge would not be successful.

                  Based on and subject to the foregoing, the discussions set
forth in the sections of the Registration Statement entitled "Certain United
States Federal Income Tax Considerations," to the extent such discussions relate
to United States federal income tax matters, are a fair and accurate summary in
all material respects of the matters addressed therein, based upon current laws
and the assumptions stated or referred to therein and the qualifications stated
therein.

                  Other than as expressly stated above, we express no opinion on
any issue relating to the Company or to any investment therein or under any
other law. We are furnishing this opinion to you for the Company's benefit in
connection with the filing of the Registration Statement with the Securities and
Exchange Commission (the "SEC") and this opinion is not to be used, circulated,
quoted, or otherwise referred to for any other purpose without our written
permission. This opinion is expressed as of the date hereof, and we disclaim any
undertaking to advise you of any subsequent changes in the matters stated,
represented or assumed herein or any subsequent changes in applicable law,
regulations or interpretations thereof.

                  We consent to the filing of this opinion as Exhibit 8.1 to the
Registration Statement. In giving this consent, we do not hereby admit that we
are within the category of persons whose consent is required under Section 7 of
the Act or the rules or regulations of the SEC promulgated thereunder.
