I have been against this since i first heard about it and am dreading it's implimentation. We go again in December, I hope it is not in effect by then.
Sounds great if you have a small group and all adults. but we will be taking a 3 year old, a 1 year old and a 3 month old. I can just about guarantee you that we will not be keeping to any schedule I may try to make. You really can't plan when babies or small children will need to eat, need a diaper change, need a nap, get cranky and need a rest, or even see something cool like the jumping water fountains outside Imagination and want to stop and play with them.
I can see it now..........sorry kids, can't look at that, we've got a schedule to keep. Sorry kid, no new diaper, just let it leak a little longer, we didn't schedule your diaper change for another hour yet. Sorry kid, i know all the advice books suggest going at your speed, but we will miss Lion King if we don't run now.
sounds fine for adult only trip- maybe. but a horrible idea for families with kids, which i think included the majority of folks at WDW.
