We always enjoy a day at Sea World and I definately wouldnt describe the park as "tatty" in anyway. In fact, a lot of it is fairly new. It depends on what you want from the day, but most tastes are covered., from thrill rides, shows and kids play centres.
Im not a huge fan of "animal shows", but, Sea World does seem to put a lot of emphasis on rehabilitation and breeding (the Manatees here, for example, are badly scarred and have been rescued). There is a tremendous amount to learn from all the animals here, and at no point did I feel uncomfortable like I have done at other zoos. Its a very clean and tidy environment., with knowledgeable staff on hand to answer any questions.
As far as the food.....we often eat at the Bimini Bay Cafe and its always been pretty good. There are more restaurants opening, but at the end of the day, you are 5 minutes from all the places on I-Drive to eat if you dont want what Sea World has to offer!
I would be interested to hear if any one as experienced "Dine With Shamu" or the new Terrors of the deep" restaurant???
Hope that helps!
Allie.
