Christmas is a time full of things to do and see in the parks... specially in Epcot with the Storytellers, the three lighting ceremony and the Candlelight Processional... then the Osborne Family Spectacle of Lights at the Studios, not to mention the special Christmas beautiful decorations in all the property and parks.
I would choose MNSSHP just because at that time of the year, there is not really much else going on. I attended it once, and had a lot of fun and a lot of Nestle chocolates! :slurp: We got our free pic and there was a parade, and it was just a cool night. I haven´t been to the MVMCP so I can´t really vote, but that would be my reasonning to choose one or the other.
