Hmmmm really..... tell me more!

I just don't want to be sitting there in a huge crowd of people not being able to move. As I said, we're not interested in the exact rope drop or anything, just wanting to be there early since we do only have 3 days in the parks total if that makes sense.
Regular Hours:
MK- Guests are admitted through the gates 20-30 min. early. Guests are held just inside the gates in front of the famous "Mickey Flower Face" just below the train platform.
There is a Welcome Show, then the rope is dropped
about "opening time."
Epcot- Guests are admitted through the gates 15-30 min. early. There is a "holding area" rope near Spaceship Earth or Fountain of Nations.
No formal "show." The rope is dropped
about "opening time."
DHS- Guests are admitted through the gates 15-30 min. early. There is a "holding area" rope near Sunset Blvd. intersection (-or- near Gt. Movie Ride.)
No formal "show." The rope is dropped
about "opening time."
DAK- Guests are admitted through the gates 15-30 min. early. There is a "holding area" rope near Discovery Island area.
No formal "show." The rope is dropped
about "opening time."
------------------
For AM EMH, there will likely be a slightly different procedure, and guests won't be admitted
as early before the AM EMH time.
MK will have at least some version of the Welcome Show before AM EMH (and not one at regular hours opening time that day.)
