MVMCP stands for Mickey's Very Merry Christmas Party. On selected nights, guests are treated to special Christmas Shows, fireworks, hot cocoa, Mickey's Very Merry Christmas Parade....most of the major attractions are open as well. Tickets are somewhere around $35.00, and MVMCP usually goes from around 7:00 - midnight. From what I can gather, DIS-Con attendees are going either the 3rd or the 8th of December.
