I had hoped the "separate gate" idea had died a merciful end, but maybe not.
Make Illuminations free? During anything resembling a busy period, I guess the "paying" customers will have to stake out spots early to beat the rush of "free" customers... Sounds like fun.
(Not to mention the fact that if everyone is jostling for position to see Illuminations, they won't be paying for dinner...)
I could live with something like doubletrouble's idea, with some kind of "discounted" after-dark ticket for WS, provided full-paying Epcot customers still have complete access to WS. (in fact, depending on the execution, I might even be in favor of it)
Certainly nothing wrong with updating Spaceship Earth, provided it remains a "no height requirement" attraction. However, it doesn't seem to be the attraction most in need of an update in FW....
As for the original concept being two parks, thats great, but were they both to be "full-admission" parks (like MK), similar in size and scope to what we see now? Perhaps FW, but I think they had more in mind that what's there now, and certainly WS is nothing close to what they would have considered charging MK prices for.
