Through Dec. 31, 2011, when you reserve a one bedroom suite at participating St. Regis Hotels & Resorts properties for a night at the published rate, and stay a second night, you will pay only $4 or local equivalent for the second night. Mention rate plan STR1904 when making reservations at (888) 625-4988.

Bottom line: This deal has been available for quite awhile but will no longer be offered after Dec. 31 (that is, if Starwood does not decide to extend the offer).
