I like the Mermaid show because of some of the effects, with the "rain" (you may feel some sprinkles or mist), the "under water" effects. Some is live, with Ariel singing, but then the puppets too. It's a nice variety. But like everyone else said, it feels heavenly in there when it's hot out. It makes for a very enjoyable break. My older kids weren't sure they wanted to see if (kind of groused) but the 4 year old wouldn't miss it, and we're going in August. I told them just wait, they will be praying to sit in that dark, air conditioned theater!
