San Antonio has a wide selection of attractions that can satisfy a variety of interests. You could easily fill your time hitting each one on your list, but I would suggest that you set aside at least a little time for aimlessly strolling about the city's downtown. The crazy layout of the streets, the buildings, the river -- you'll come across unexpected sights like, for instance, the Bexar (pronounced bear) County Court House, which, though not remarkable enough to merit specific listing among the city's attractions, still is quite attractive and lends an appreciation to the city's character. Also, a couple of plazas lie almost forgotten, one of which in the old days was the scene of a running battle with a Comanche raiding party.
Before you visit any of the paid attractions, stop in at the San Antonio Visitor Information Center, 317 Alamo Plaza (tel. 210/207-6748), across the street from the Alamo, and ask for their SAVE San Antonio discount book; it includes coupons for everything from the large theme parks to some city tours and museums. Many hotels also have a stash of discount coupons for their guests.
