My sister and I went to SeaWorld, San Diego last year. We had been there once before, as children, but wanted to see the place again. It was okay. I guess everything looks bigger and better as a child, so I was a bit disappointed as an adult. I expected more from a world famous destination. I didn't remember it having so much trash on the ground as a child, or so many unfortunate smells. The exhibits were pretty much as I remembered, but I can't help but feel sorry for the marine mammals. I personally don't think the orcas or dolphins get enough space or enrichment in their tanks. I have a feeling we may be boring them to death. Plus, I read somewhere that the original Shamu was taken rather violently from the wild. The manta ray exhibit was alright, as was the starfish area.
There is a new show there called Cirque del Mar (yes, it is a rip-off of Cirque du Soleil) and it was pretty lame. I'm not easily impressed by mediocre costumes or someone's basic diving ability as I was on both swim team and in theatre. The performers are supposed to be some sort of fantasy sea creatures, but they looked more like rejects from Mystere. I guess it was popular with small children though.
My favorite part of SeaWorld had nothing to do with the sea. Honestly, I enjoyed the Budweiser Clydesdale barn more than everything else. At least the horses looked healthy and well cared for.
