Do you think the hours listed on TouringPlans.com for August are final? I'm looking at a possible trip on August 19-25. Other than one Extra Magic Evening at MK, the parks all close between 7 pm and 9 pm. Was hoping for some later nights to be opened to avoid the heat of the day. Does anything think the hours will be adjusted for more late night hours?
I'm going the week after you, and am noticing the same thing. I think that they will adjust a little bit the closer to the summer we get.
Nothing is final - although the hours listed are the current "official" hours, WDW frequently updates them. Keep an eye out for changes as it gets closer to your trip date.
