I was just at MVMCP. At around 6:00 I asked when Haunted Mansion would open and was told next week. At 10:30 someone told me that they had just ridden it. DH and I went over and rode it. Very short wait. There are some changes with some of the ghosts but I don't think anything major has changed.
I rode it tonight also. I was so excited to see it open! I asked a HM cast member when they opened and he said they haven't "officially" opened back up yet.
Ugh. It's my last day. I'm scheduled in epcot and don't have hoppers and even if I upgrade I don't know if it's worth the travel time. These are the moments I miss easy breezy disneyland.
