Another thing you'll have to get used to is the humidity, every time I visit SA it takes me about an hour to get used to it.
When did the Alamo Drafthouse come to town?
San Antonio is a great place to visit, but I'm not sure if I'd live there again. The housing is dirt cheap, especially compared to San Diego. There are quite a few things to do in SA to keep you busy; you can visit tourist traps like the Riverwalk, Rivercenter Mall and of course the Alamo. There’s also Fiesta Texas, Seaworld, Tower of the Americas, many museums, the symphony, the zoo, botanical gardens, any many other interesting places. Of course SA has quite a few clubs if you’re into that scene and there’s also 6th street up in Austin which is a short hop away.
The food there is great, at least IMHO. Texmex is the local flavor and the BBQ there is awesome, lots of great places to eat cheaply. Also SA doesn’t shut down at 10pm like a lot of places I’ve been. You shouldn’t have any trouble finding a bite to eat or do some shopping in the middle of the night which is nice.
If you have any specific questions feel free to shoot ‘em my way.
