I guess I would love Sea World if I wasn't comparing it to Disney...
FULL INFORMATION: I haven't gone in a LONG time, so I'm sure it must have changed.
Overall: I remember feeling like it was dirty. Overflowing garbage cans and suddenly remembering things like lots of bugs and seagulls in Florida.
Rides/attractions: All this time I still remember Atlantis ride - that was amazing. The Shamu show and the people mover through the shark tank were incredible. Lots of touch tanks for younger kids (I had a 5 year old, 4 year old, and 18 month old with me) and places to buy herrings and feed things like dolphins and seals. Tons of touch tanks and a nicely themed kids area.
Those herrings - of course - were what attracted all the "natural wildlife". Not just pesky seagulls but really opportunistic beasts which took my daughter's french fry out of her hand while she was eating. My (now ex) husband eventually just sat there with a water gun shooting at them so the rest of us could eat in peace (thank GOD my 5 year old nephew was "armed")! And then we went to feed seals and there was a large (I mean very LARGE) aquatic bird of some type (looking almost like a pelican but it was brown and white with an enormous mouth) sitting in the middle of one of the paths badgering people for fish. Probably now my kids would enjoy it but at the time with 3 small kids and this bird bigger than they were - it actually made me nervous (I admit that I am not a bird fancier - I will admire them from afar). I mean, this wasn't one of the park animals which was under medical care allowed to wander the paths with a handler near by as an attraction - it was a wild animal keeping itself alive.
I also had a problem with the Budwiser Horses - which I didn't expect to have. I know it's a Busch park so they plug their products (I'm not a teetotaler by any means) but I did have a reaction to having alcohol and things meant to attract kids being promoted TOGETHER. The horses were beautiful but so out of place in a park devoted to marine life, it just left a bad taste in my mouth.
I also remember sitting in one of the smaller theatres watching a dolphin show - great show, but I could see the parking lot of the mall next door from my seat at the top of the stadium seating. It kind of distracted me.
We got back to Disney (we were staying on property) and went to Magic Kingdom the next day; I was sitting there with my husband in Tomorrowland just enjoying the Disney atmosphere - no "wild life", no seagulls stealing our food and only the random bee here and there - wondering how it could be so different just down the road. At that point he looked at me and said "I'm never going off property again".
So like I said, if I wasn't comparing Sea World to Disney, I'd probably love it. There were a lot of great aspects to it and my kids have gone back with family and had a blast; my daughter came home from that trip wanting a fish tank, now wants to be a marine biologist, and her dream internship is one at Sea World. But I probably wouldn't do it again, at least not in a vacation where I combined Sea World and Disney. I go to WDW for more than just rides.
