"The new park will be called 'DisneySeas', and will be based largely on the Tokyo DisneySea park, but this time with a healthy dose of marine life shows. There are already big water tanks backstage at Disney's Animal Kingdom where Disney is training dolphins, killer whales, and other marine life for the Disney quality shows that will become the focus for the new park.
The Fifth Gate location on the 120 acres directly adjacent to the Magic Kingdom and across the Lagoon from Wilderness Lodge. The recent construction at the Contemporary is to help handle the expected increased hotel capacity the new resort will bring. The location also takes advantage of the monorail line. Construction on a new monorail station right overhead the existing bus station has already begun. A people mover will carry guests from the station to the DisneySeas entrance. The current parking lots will be slowly converted to multi-story garages with moving walkways similar to Universal Orlando. Capacity will be approximately double the current parking lots, with space left over for expanded ticket book and transportation center (with shops and dining).
A few guests have emailed me and reported seeing 'sight-line' balloons rising from the area adjacent to the Magic Kingdom recently. This also confirms the rumor, so Disney must have decided the time was right to make the announcement. "
From what I can see from the responses to the post, this last one is a huge April Fool's Day joke. I guess we'll have to hear it from Meg to know if it's gossip, rumor or truth on the fast-track.
