Im going with my sisters and parents in the summer and although we;ve been many times its still great to hear other peoples tips or favourite things to do....please share
Epcot: Soarin
DHS: Tower of Terror (also love Rockin Rollercoaster and Indy Stunt show)
Animal Kingdom: EE (safari close 2nd)
Magic Kingdom The mountains (also just staring at the castle is lovely)
Grab some Casey's and a Dole Whip, then park yourself down and watch the 3:00 parade from a table next to Main Street. Honestly, nothing better than my favorite food and watching Disney magic float by.
