We used 7 of them at Sea World San Antonio on Aug. 4. They just scan them and in you go. It was great! I could kick my self though. Right before we left I went to customer service and ask how much it would be to upgrade my ticket to a second day. The guy at the window was not sure, so he asked the manager on duty with him at the time. They said I could upgrade my ticket for $3.24 plus tax per ticket. I thought wow thats great. When I asked my kids if they wanted to come back the next day or go to splashtown it was 4 to 1 for splashtown. I thought, fine how bad can it be. I paid $128 to get into spashtown for all 7 of us. And that was with the $7 off Tyler club coupon. We could have went back to Sea World for about $26. Next time I won't take a vote.
