One thing to note: Wed that week 5/26, they are having a private Wishes event for the DVC Member Homecoming beginning at 8:30. I'm going this week, to, and I am trying to figure out which days to go to the parks (only doing 2 or 3 days this trip). I cna't find out for sure if this event means the whole park is closing early or not because WDW website still shows it open til 9 PM.
Anyway, I am leaning towards going Monday 5/24 to MK. It's the day after EMH, so that's supposed to be a good day to go. Tuesday 5/25 is EMH, and also Epcot is closing early to host a private Illuminations party for the Member Homecoming, so MK and MGM are open late. My plan for Tuesday is to start out at Epcot, leave for a break and head over to MGM later in the day. Hope to hit ToT and RnRC several times while everyone else is at the first Fantasmic, and then go to the second Fantasmic at 10:30.
