We went last year and had a blast. It seemed more crowded than the "not so scary..." but still less crowded than a regular day at MK. The characters dressed in Christmas garb was neat, and the parade was cool. We will watch both this time! We are going Nov 29 and chose the Tuesday as to stay away from what could be a more crowded night closer to the weekend.
Don't forget you can get in at 3:00pm with your party ticket. It might save you a day of you hopper pass if you want to do DD that day and not use a ticket. PM me if you want any more info.
We loved it - it was very crowded...we went on a Thursday night I think. It was fun to see the parade/shows...which is what we focused on. I think the lines were long, but we were there for 15 days, so we just did stuff that was only offered during MVMCP. Oh, one thing we didn't do that we just plain ol' forgot about - special merchandise is out, so you should budget some time and money to shop! Can't believe we didn't...we shop A LOT when we are there!
Enjoy!
