Dinoland should remain Dinosaur-themed, but they should tie it into SEA and an exploration of a "lost world" theme. A set of explorers who stumble upon a preserved jungle that houses real life dinosaurs, or something along those lines, could be fun. They set up a research institute, send people out into the jungle to do research, etc. You'd barely have to change the existing Dinosaur ride. Replace the carnival area with something that has a Lost River Delta in Tokyo DisneySea vibe, add in a new E-Ticket and a new kid friendly ride. You could even have the story be that it is set in the Amazon and tie in a few more animal exhibits. Then you've got an incredible new land that fits well in Animal Kingdom, is a nice bookend to Pandora, and is still distinctly Disney
