Our 24-kickoff to The Coolest Summer Ever has officially concluded here at the Walt Disney World Resort. A screening of “Tomorrowland” with 500 of our readers? A few trips on Seven Dwarfs Mine Train? Two performances of “Main Street Electrical Parade”? Dole Whip at 3 a.m.? I can’t imagine a better way to kick off what will for sure be the Coolest Summer Ever at Disney Parks.
