We just got back last week, and took the kids there for the first time. I loved it!! It's such a different atmosphere than the Disney Parks...not many rides, not many lines...The theaters for the different shows accomodate large groups of people, so unless you wanted a 'splash zone' seat, you could pretty much just walk right in within 10 minutes before showtime. The two rides were lots of fun. The Journey to Atlantis is similar to Splash Mountain (although, not as scienic, per say, almost kind of corny). The Kraken was VERY thrilling, lots of loops and twists. Unless you REALLY like those types of coasters, I would avoid it. We did the online special, BOGO day free ticket.
We got there at opening (9:00) and did the two rides first, no wait whatsoever. We were able to ride quite a few times. At about 10am, a line started to form, and thats when we left that area and walked towards the shows. The Shamu and the dolphin shows were really fun, the mime at the sealion show was hilarious (as someone else also said). We ate at the Hospiality House Deli...not bad for the prices. The food was also good, though not alot of choices. The FREE beer made up for it, though!!! We actually went back for the second day and fed the dolphins-a must do, esp. for the kids-and saw the Pets Ahoy show, which was very fun. All in all, we really were surprised at the amount of time we spent there. There really is alot to see and do there, and the best part is that you do it at your own leisurely pace. Enjoy your trip.
