Just wanted to reply that we had a GREAT trip! Followed a lot of your suggestions. We stayed at Hotel Contessa on the Riverwalk for 3 nights, loved the hotel & the location. Riverwalk was great and loved Casa Rio, we ate there twice. Did the Tower of Americas, Hemisfair park, the Alamo (kids were totally bored), and the River cruise (fun!). Went to the Caverns in New Braunfels and really enjoyed them. Also did the rope course there which was a lot of fun. At lunch at the Gristmill which we loved and visited Gruene & Gruene Hall. We then moved to the Hyatt Wild Oak for 4 nights. This place was FANTASTIC! Pools, waterslides & lazy river were all so much fun. Also had access to the Hyatt Regency next door for even more pools, waterslides, & another lazy river. We visited Aquatica & Seaworld. Both were much smaller than the ones in Orlando but there were no lines at all so we got to ride everything multiple times. Visited Kemah Boardwalk before our flight out of Houston & had a great time there as well. Overall we had a wonderful time.
