We go every July now (used to go for Thanksgiving, until the first week in Dec-- those were the days--- weather perfect, CP, holidays, etc) -- but cant take the kids out of school anymore) --- so, we go Mid-July now
Only part of summer in Disney that we've sworn off is late August- around Labor day===. that was unbearable !!!
Honestly, we live in NYC, and the summers aren't much better--- hot and humid as heck !! Would rather sweat with the Mouse !!!
