I went with DH last year. We had fun, but I had placed it at the end of our first day and we spent a lot of the time riding rides etc. instead of doing the party stuff. We did see the parade, which was a lot of fun! The "snow" cracked me up. I'm from MI. I'll take soap snow over real snow any day!
That said, DH isn't big on Christmas, and mostly goes to Disney to humor me.

I don't think I'd do MVMCP with him again.
My mom on the other hand...
that woman could moonlight as one of Santa's Elves! She loves Christmas, and Disney. This is going to be a majorly nostalgic trip for us. I hadn't originally planned on going, but our last night is going to be a party night, so we'd have to clear out of MK by 7:00 if we don't go. I've learned that I really need to start and end my trips with MK, so it seems like it would be the perfect thing to do. We also don't have park hoppers, but with the party tickets we could do the morning at one of the other parks, and then bounce over to MK for MVMCP.
I think I may have just talked myself into it!
ETA: The original plan was to maybe do La Nouba our last night. But that would cost almost twice as much, and I just saw it last year. Plus, ending the trip with a special parade and Christmas Wishes.... um. Yes please.
