Save your disappointment and stay at the Hyatt
I am a hardcore Hyatt resort fan, but I was really looking forward to staying at this hotel. What a huge disappointment!
Let me get right to the point:
Pros - They have a shuttle that will take you to Fiesta Texas and the Shops at La Cantera. They have an adults-only pool, and it's a large pool. They have a Looney Tunes breakfast, where Looney Tunes characters come out and visit with your kids, and the staff there were exceptional. 
Cons - Customer service was soooo bad. My $1000 for two nights will go somewhere else next time. The pool for the kids is kind of small. And there's no lazy river...something that I've gotten use to with Hyatt resorts. Those lazy rivers are life-savers...the kids never get tired of them! My real problem with the hotel is that the customer service was so horrible. I complained immediately, but the manager didn't attempt to contact me until the night before we left.
