I'll ask a CM when we go next week if they are planning any changes to the EMH. We went in May, and 3 weeks before the trip they tested evening EMH and cancelled some of the morning times. Completely screwed up my PS's ect. I had to redo everything. Thankfully, I was on the disboards or I wouldn't have had a clue. Also, it wasn't that crowded so I was able to reschedule my PS's to new days.
I'm also thankful that Nextell doesn't charge long distance calls on the weekend. It took about an hour to reschedule everything.
So keep your eyes on the board for anything new.
