I just checked last year's times on Allearsnet and it was from &pm to 12am, so the times have not changed. You can still get in a lot of Disney fun at MVMCP in 5 hrs. Just go with a plan. That is what we do with MNSSHP, and we have a blast and haven't missed a thing yet. I love it and definitely get my money's worth, and my DD wants to go to MVMCP. Maybe in a few years, we will get the chance.
