I live in SA. I disagree that May is miserably hot. Yes it is warmer than Mass but not unbearable...Aug is unbearable.
I live in SA as well and ITA with you. May is a walk in the park compared to August
Anyway, the previous posters have pretty much covered all the biggies. As far as the theme parks go, I personally enjoy Sea World much more than Fiesta Texas. But that's mostly because I'm not much of a thrill ride type person and that is mostly what Fiesta Texas is. Plus, I like the employees and atmosphere better. But my younger sister loves Fiesta Texas so it's really all a matter of personal preference
If you like shopping try La Cantera shopping center. It's right next to Fiesta Texas actually. It has a LOT of nice stores. It's an outdoor place but even though it will be warm all the stores themselves are air conditioned as well as the food court.
The Riverwalk is definitely a great place to go. There's plenty of restaurants down there to eat at if that's what you'd like to do. Although if you want Mexican food, don't eat at the Riverwalk. They overcharge for food that's not worth it. The Alamo is really neat and if you have time, the missions of San Antonio are interesting as well.
Food wise, there's a ton to choose from. If you like Mexican food I would recommend Pappasito's, Las Margaritas (downtown), Panchito's, or Los Barrios. You can use MapQuest (although I prefer Yahoo!maps) to find directions to any of these places. It's not hard to get around San Antonio at all. We have some great sushi places if you like that. There's a place called Sushi Zushi that my family really likes. And if you have non-sushi eaters they have a regular menu as well. Just a suggestion

If you like seafood, Pappadeaux is great. Lots of cajun themed food there. For Italian we have the basic run of the mill stuff like Macaroni Grill and Johnny Carino's. But there's a small place called Little Italy where we get our pizza from that has really good regular food as well. Like I said, there's a lot to choose from here.
Oh, and if you're into art at all the San Antonio Museum of Art and the McNay Art Museum (my personal favorite) are both really awesome. The Institute of Texan Cultures is cool too. It's basically a museum but they always have cool exhibits there.
Hmmm...as far as hotels go, I really can't help you there. I've never had a need to stay at a hotel here. But I've heard good things about the Hyatt Hill Country Resort and the Marriott downtown. I've also heard the Valencia is nice. But I'm sure those can get pretty pricey and I don't know what your budget is.
Anyway, I'll wrap this up now. I talk a lot even on the internet apparently

Hope that helped a little, have a great trip
