Disney isn't joking around about keeping people there after dark huh? RoL and The TREE look amazing. The Mexican Theme park Xcaret does the street party thing before it's night time shows to " transition" people and it works really really well. Xcaret is actually super similar to AK in theming so I bet this is where they got the idea.
I wonder if all of these night time experiences will take the pressure off of the other parks at night? Specifically MK??
