I went on my Disney Experience to order Magic Bands and looked at my ADRs. They had my Candlelight Processional Dinner on the same day as MVMCP. That wouldn't work. Luckily they still had CP availability so a small disaster was averted.
The point is, check your ADRs- they do occasionally screw them up.
