Here’s the map from last night. We were able to enter the park when we arrived 30 minutes early.
You receive 3 snack credits for use at Regal Eagle, Connections Cafe, Sunshine Seasons, various snack carts around the park, and festival booths (with the exceptions of Mexico, China, Italy, Japan and France. The list of dining locations is on the map, along with qualifying items. Festival booths close at 10.
The back of World Showcase also closes at 10 between Morocco and China.
Cosmic Rewind stayed at 30 minutes pretty much the whole night and was sometimes a walk on. Other attractions were mostly walk ons except for Frozen Ever After which was around 20 mins the whole night.
I did not meet any characters (not my forte) but the locations are on the map.
Free ice cream was seamless and was offered at 4 locations (map says 3 but I found an extra one at the club cool snack cart). If you go to the one by creations shop you can get a free cup of ice water as well.
Any other questions ask away!
