I don't like the animal shows at Sea World, to be honest. They just don't interest my family. However, Sea World would be interesting to me if they had a giant tank like they do in Georgia with whale sharks and other large fish. That is just breahtaking. Look up videos on YouTube of the Georgia Aquarium. There is nothing like this at Sea World.
To me, this is the kind of thing they should focus on in the future. Move away from the animal shows and instead invest in jaw-dropping displays. Build the world's largest tank. Build one so big they could even keep a great white shark in it. Do something like that and I'd be interested in Sea World again.
The Georgia Aquarium is amazing, but it is waaay too crowded most of the time. The Georgia Aquarium actually seems to be shifting toward Seaworld's usage of shows. The G.A. has a large dolphin show and a 3d show. The aquarium is also subdivided into "lands." Despite this, Seaworld's use of better shows, well themed areas, and rides makes me enjoy visits to seaworld much more than visits to the G.A.
