Get a free night at posh Rosewood Hotels & Resorts

Urban refinement in the heart of the city? Pampered indulgence at a secluded hideaway? You can extend your posh getaway with a night on the house at most of the hotels in the Rosewood Hotels & Resorts luxury chain. Your stay won’t be cheap, but at least it will be cheaper.

The deal: The “More Rosewood” promotion gives a third night free when you stay two nights at selected hotels, such as the San Ysidro Ranch in Santa Barbara and Sand Hill in Palo Alto in California and others in Atlanta, Dallas, New York and Vancouver (opens in March 2011). The CordeValle, south of San Jose in San Martin, offers as many as seven nights for the price of four.

The threshold to qualify for a free night at destinations in the Caribbean (Antigua and the British and U.S. Virgin Islands) and Mexico (Los Cabos; Riviera Maya; and San Miguel de Allende, opening in February) varies between three and six nights, depending on the resort.

Note: The cost of the free night is not reflected in the reservation, but it will be deducted or refunded at check-out.

When: Good for stays in several room categories, Jan. 3 through May 27.

Tested: For a three-day stay midweek at the San Ysidro Ranch in January, the hotel website and telephone agents recently offered room rates starting at $795 per night, plus tax, with the third night free. The effective rate with the discount: $530 per night, plus tax. A four-day weekend stay at Las Ventanas al Paraíso in Los Cabos was priced at $685 per night, plus tax and resort fee, for the least expensive room, with the fourth night free. The effective rate with the discount: $514 per night, plus tax and resort fee.
