Drives me nuts too!!!
I think many of us are able to roll with what Disney throws at us, and move on. Okay, we all get hours can change, and RoL ran into serious tech issues etc, but what is happening now is like Disney telling us, "sorry we are in over our heads, and really don't know what we're doing, and hopefully at some point in time we'll figure it out.'

Disney knows we plan around EMH. We wrap park days, ADRs, and FPs around EMH, and then they come along and pull the rug out from under us....what the heck???? As it stands now, we cannot count on any of our plans staying put.
Why even promote advance planning any longer when park hours and events are so unpredictable. Vent over.
On a lighter note, happy Mother's Day to all our wonderful Disboard moms!
