FWIW, Here's my $0.02:
The major expansions at WDW thus far have been mostly well-played. However, they have reached a point now where no further mass expansion is needed in the short-term...i.e. Flamingo Crossing or a 5th Gate. TDO would do well to go ahead complete the Pop Century - Golden Years site. Beyond that, TDO needs to focus on improving/expanding what is already there. DTD - especially the former Pleasure Island - needs a lot of attention. There has been a great deal of discussion on these boards about the needs of all 4 theme parks (MK still has needs that the FL expansion will not be seeing to - AL, to point out a glaring element). And I think, some investment needs to be put in place by TDO to eventually eliminate their intra-resort reliance on buses for guest transport.
So, bottom line: WDW's needs have changed, now is the time to focus on what's already there and make it even better for a great big beautiful tomorrow.
