I had the opportunity to visit DisneySea last year, and it absolutely blew my mind. Imagine the detail of DAK at a scale bigger than Epcot, and you'll have an idea of what it's like. If you ever have the chance to go, DO IT. Sooner rather than later, because IPs are starting to take over and mess up the near-perfect theming. Just use the crowd calendar recommended by TDR Explorer to make sure you go on a quiet day, or you'll see crowds and queues like you've never seen. Journey to the Center of the Earth, and the entire Mysterious Island area - brilliant.
