Two different holidays. You can do MVMCP and Jollywood Nights on back to back days. We have done that several times but being older it’s a killer schedule.

The first Christmas party has traditionally been the friday of the next week after Halloween. So this year (again nothing has been announced yet) but I suspect the first MVMCP would be Nov. 6th, 2026. There will probably be a MNSSHP on Friday Oct. 30th and Sat. Oct 31st. Again these are ONLY MY SPECULATION from past schedules.

I assume the question is actually about an overlapping Halloween and Christmas trip?

In which case, the last MNSSHP will probably be October 31, 2026 and the first DJN will likely be November 7, 2026. So that plus arrival/departure.

You would only need 2. One for each. They are a separate ticket that they allow you to get in the park at 4 pm, park closes at 6pm and you stay until 1 am (MK anyway). But they do not have them everynight. MNSSHP is a few times a week and I am not sure about Jollywood nights. We just did our first MNSSHP this passed December and we got everything we wanted to do in one night. However we forgo meeting characters that you can only see at the party in place of the other photo ops, shorter lines, and food. So i guess 2 nights if you wanted to spend the money would be more than enough
