According to disney's website the description of MVMCP says they will be showing Wishes. I'm not sure if it will be the regular Wishes or maybe a special holiday version. I guess I will just have to find out when I go to MVMCP on 12/2!!!
What happened last December was at 9:15pm, they would shoot off the Fantasy show (now Wishes). Then go into the MVMCP fireworks. These are different, as they are shot off in the round, as well as over the castle and are played with holiday music. If I can remember, it was like 6 different locations. Alot of these are green and red for the holidays.
A great place to view both of these is on the beach at the Polynesian. You have a straight shot of the castle and all of the fireworks.
