Sweet Maxine - we did enjoy MVMCP. I'm not sure how to judge how crowded it was. We chose not to try to do rides but to do the shows, parades, and other special things. We skipped the early parade because it is definitely more crowded. We got a good place to watch the first show in front of the castle about 15 minutes before it started. It was crowded around Main St. and the hub and the walkway to Tomorrowland for the fireworks, just because that's where everyone stands. We watched the second parade from Frontierland, and there were still good viewing spots to be had when the parade started, so I would recommend that location. The December 17 MVMCP is sold out, and the one we went to wasn't, so I'm sure there will be more people there for yours. Take Disneyfan1980's advice and try rides during the first parade, if you want to do rides. Otherwise, just have a plan for what shows you want to see at what times, and enjoy the atmosphere. We didn't try to get our pictures taken because that just isn't a big deal to us. One tip I've heard for avoiding the lines for this (there are only two locations) is to head for the location at the back of the park as soon as possible and get it taken care of early.
