The worst part of DCA is Paradise Pier. Screamin can stay but I was in charge. I would gut Paradise Pier. Fill up the Lagoon and get rid of all the attractions and shops and start from the beginning again. It looks so cheap.
I would bring the Aerosmith Rock and Roll coaster from MGM for a start.
I also would change the name of the land as well. Any ideas for attractions and a new name?
