For us it was quick. We were able to sign up and then get back into the holding area with the rest of the EMH resort guests. All EMH guests were let into the park about 7:45, we went to Jedi signup, which is past Hollywood & Vine, while the other guests were held near the stage area. At 8:00 everyone was let past the stage area to go onto their desired locations.
On a side note - DD10 only likes to ride Toy Story, so the other rides are a non factor for us and the crowds only affected us while awaiting to see the March of the First order and the Star Wars stage show (the exact names escapes me at the moment).
As others have posted, this is all subject to change. This thread has helped so much in planing everything Star Wars, so if something changes, I think this is the place to read about it!!!
