A San Francisco boutique hotel for $66 a night? That's the rate you'll pay at several Joie de Vivre Hospitality hotels when you book the "Endless Indian Summer Package." If you stay two nights starting at $99 a night, you get the third night free at Hotel Bijou, Commodore Hotel, Phoenix Hotel, Savoy Hotel and Shannon Court Hotel. At the Maxwell Hotel, Hotel Rex and Hotel Del Sol, the package is based on a $135-per-night rate; it's $155 at Nob Hill Lambourne and the Archbishop's Mansion. The package is good for stays Sept. 1 to Oct. 31, subject to availability. It includes cable car passes and discount coupons for shops and restaurants. For information about the hotels, see www.jdvhospitality.com/hotels/sanfrancisco.html; but you must call (800) 738-7477 to reserve, and you must mention the package by name when you book.
