My husband, 6-year old son, and I are traveling to South Padre Island for a few nights. I'm trying to decide on a hotel. I've narrowed it down to the Hilton Garden Inn and the Schlitterbahn Resort, and am trying to decide what reservation to keep and which one to cancel. I thought that the HGI would be nicer, but the Schlitterbahn resort would be more fun. A lot of the recent reviews for Schlitterbahn Resort are very positive. Any suggestions?
