Trying to "do" all 4 parks in one day during Thanksgiving Weekend, about the most you'll accomplish is bragging rights that you did it. But if you're going to try to do it, at least make it as pleasant as possible by using Disney transportation as much as possible. Pick a morning that has early EMH at MK. Your plan is staying at Wilderness Lodge? Take the ferry. Get there and do as much as you can. Once the park starts getting full, or you've done what you want to do, leave via monorail to Epcot. Hit whatever you intend to hit there, and then ferry to the Studios. Bus to AK from the Studios. if you're exhausted by then, bus back to WL. Otherwise, bus back to MK or any other park you didn't spend enough time in (which will be pretty much all of them). If you do end your day in MK, bus back to WL, and consider the boat rides and monorails part of the "attractions" you've done that day, as opposed to all that extra time in your car.
The only downside to this plan is that there's a good chance AK won't be open too late, since it will be getting dark pretty early by then. But maybe you'll get lucky, and it will be a day with early EMH in MK, and late EMH at AK. The plus side includes a: You won't have to drive back to your resort after an exhausting day, and b: you won't have to risk having to park pretty far in a theme park lot, eating up a lot of time just getting to and from the main gate; c: you never know if/when Disney's security team will decide that it's a day they really need to enforce parking rules. Your plan to park at GF, monorail to MK, then Monorail back to GF*, drive to AK lot, then drive to Boardwalk for Epcot and the Studios? Technically, not really allowed, though who knows if Security will call you on it (it is a discussion for another thread, and has been, many many times). You're only supposed to park in the lot of a resort that you're not staying in, if you're there to dine or enjoy the amenities of that resort. And you're officially given a three hour window to do it. Just because you probably won't be given a ticket or towed for parking where you ought not to, doesn't mean you definitely won't, and won't THAT cut down on your plan to tour all four parks in a day? :lol:
* - if you insist on parking at GF, monorail TO MK, but you'll probably save time taking one of their water launches BACK to GF, since the monorail will first go to the Contemporary, the Poly and the TTC before going back to GF.
