For me the two reasons (and the only two reasons) to go into DCA are the Tower of Terror and the Zoetrope. I was totally mesmerized by how cool it was. We all thought it was neat how everything has its own sound too, if you listen for it.
The lady at the front says it spins 2 1/2 times per second, and that the little green alien waving to you at the front has the most Gs..... 7Gs, in fact

I hope they make more of those things with different characters, seriously. I could spend an entire day in a room of spinning zoetropes.
