I don't know, I'm no Disney regular and just started frequenting these boards a couple months ago in order to plan our one-in-a-lifetime trip to WDW, but these changes lately seem to show a real nasty disregard for guests who already have trips planned. Since they have created this situation where you have to plan stuff 6+ months in advance (which is crazy enough!), they could've at least posted a start date for these changes much further in advance. Not only do these poor April/May folks still have NO info on ROL, now they have days with "after dark" events that will affect crowd levels on MK day and who knows what else.
We really went back and forth about whether to stay on site or not for our trip, and in the end we decided to just because of the EMH - I really hope they still have them in Oct! As far as this crazy advanced planning goes, I guess we will just plan our days in any order we want since there is no telling what hours/perks will be like in the fall...
I am always the vacay planner for our family and I can honestly say this is the weirdest planning experience ever - and we are still over 6 months out! Can't imagine another park pulling this stuff.
