Hey Howdy Hey Leah and welcome to planDisney!
There is nothing like walking down Main Street U.S.A. when the park is all dressed up for the Holiday season to get you in the spirit. I am happy to hear you will also be getting the full experience of attending
Mickey's Verry Merry Christmas Party! Thank you for your questions about entering the parks and wristbands. You've got a friend in me who can share the details with you!
On the day of your Christmas party,
Guests are allowed in the parks starting at 4:00 P.M. If you plan to get to the parks around 3, I suggest waiting an hour or visiting the parks earlier. This way you can either save your park ticket for another day or you can get the most out of your ticket with a full day in the park.
As you have mentioned Leah, Guests with valid ticket entry to the party will receive a special wristband for the evening. These wristbands will start to be issued at 4 PM when the party entrance officially opens up. This typically happens at the front of the park and you will see Cast Members guiding Guests to the location to pick them up. You will have to show proof of your party ticket either with your MagicBand,
MagicMobile pass or Key to the Kingdom card. Once you get your wristband, be sure to experience any of your "must-do" attractions before the party starts.
During the party, there is going to be so much going on that is unique to the party experience that you are not going to want to miss. Of my favorites, you should get your spot for
Mickey's Once Upon a Christmas Parade. You will be able to see all of your favorite characters decked out in their Holiday best as well as a visit from the big man himself, Santa! If you do happen to get a spot on Main Street U.S.A. you might even have an extra special surprise for the full immersive experience (no spoilers here)!
I hope this information is helpful so you can better plan for your day during the party and when using your tickets. If you have any other questions please let us know, we are always happy to help!
To Infinity and Beyond,
Nick
