I've not booked yet but will be going. Just a tip guys. If you dont buy the flexi ticket but still fancy going to Sea World (which you must because it is just amazing), just pay at the gate or buy a single day ticket. As soon as you go into the park direct on the left hand side is Guest Services. Go up there and hand in your day ticket and they will validate it for the next 6 days free entry. Its fab if you have little ones and they get fed up walking round, you don't have to panic as you can just go again. We ended up going three evenings......we loved it sooooooooo much.
Also when we went to Universal studios the park was really busy and we didn't get on all the rides....so when we were leaving the park we nipped into guest services and thought we'd try our luck. We mentioned how we had not got on alot of the attractions and they validated our ticket for another visit......you have to love the Americans...they sure know customer service.
You will all have a fabulous time...the place is AMAZING.
