Yippee! Only 2 days until vacation! (San Antonio)

[Shrek]

The boy wanted a ski trip, but the wife wanted San Antonio because some of her friends recommended it. They fought a pitched battle, but the boy was badly overmatched and the wife prevailed (I myself am not allowed an opinion and am expected only to keep quiet and drive the van :) ).

We've never been there, so I'd appreciate suggestions from anyone who lives nearby or has visited before. We're staying at a hotel on the Riverwalk, and we plan to do Seaworld and The Alamo.

Anything else that's a must-see? Anything to avoid at all cost? We'll be in town for about a week.

I checked the extended forecast and next week looks fabulous -- highs in the upper 70s to low 80s. I can't wait!
