Vacationist, the hotel flash sale site from LuxuryLink and Travel+Leisure, has a great deal on the InterCtontinental Hotel San Francisco — a very swanky new (opened 2008) hotel; the closest deluxe hotel to all of the Folsom Street Fair festivities.  Standard Rooms start at $129 ($139 for Folsom Weekend), Deluxe Rooms are $189/night.  Small historical tidbit: InterContinental Hotels is now part of Bass Hotels, which traces its roots back to 1777, but was started in 1946 by Pan American World Airways, to provide suitable accommodations for passengers arriving in foreign lands on Pan Am's Flying Clippers.  Click on the Vacationist link or here for your invitation to join and book on Vacationist.
