As much as i'd like to say "cross valley woodie", I think our future plans need to be slightly realistic.
Mutiny Bay is clearly in need of some development, especially The Flume, i'd propose the removal of both The Flume and the Burger Kitchen. Move The Blade over from FV and place it in area in which the Burger Kitchen was, a re-theme to match Mutiny Bay would obviously be needed.
The rest of the area in which The Flume was; install either a Mack super splash or water coaster, I feel it's probably necessary for the replacement of The Flume to be a water-ride of some kind to fill in the missing gap of a "log flume" at the park.
I'd then remove Submission and re-locate Enterprise to the Dark Forest, it'd be pretty easy to theme Enterprise to the "Forest" theme, nothing some plastic branches and paint won't do. I'd then add something such as a top-scan to fill in the area.
And ofcourse, as previously mentioned, the path between FV and Hotels would be ideal for the 'Disney Street', and a big emphasis on entertainment, the lack of it currently is shocking when you compare it to the likes of other European parks.
