We went last night at MK. Got in at 6:19. They have a special sign/area at the gate where they scan your ticket and greet you. Probably could have gotten in sooner.
My suggestion, set up three FP for 6:30-7:30, 7:35-8:35 and 8:40-9:40. That way even if they don’t let you in early you can still catch them all. We did Jungle Cruise, BTMR and Haunted Mansion, filling in the gaps with Pirates.
We had no issue with snack availability. I even got a Coke at 1:05 after getting off the last ride
It wasn’t as deserted as some have said, but we never waited more than 2 mins for anything after 10pm.
My only complaints, not to do with DAH, why is it such a long walk in and out of Space Mountain? We would have road it more, but it’s just too much walking. And why is People Mover even still there? That has to be the lamest excuse for an “attraction” there is.
