Hi Kelsey,
Thanks for stopping by the Disney Parks Moms Panel with this excellent question!
I believe you are referring to
Mickey's Very Merry Christmas Party at Magic Kingdom Park. If that is the case, I'm sorry to say that as of this time, it is not possible to attend the special event without purchasing party tickets. On party nights, the park closes to regular-ticket holders at 7:00 p.m. After that, it is available only to Guests who have purchased admission to Mickey's Very Merry Christmas Party. Even if you are visiting Magic Kingdom Park the day of the party, you will not be able to remain with just park admission tickets. Once the clock strikes 7:00 p.m., Cast Members will check to see if Guests have the special party ticket wristbands. If you do not have them, then they will escort you to the park's exit.
It sounds as though you would like to partake of the incredible holiday festivities during Mickey's Very Merry Christmas Party; I suggest purchasing tickets as soon as possible. These special events do sell out very quickly, as they do limit the amount of Guests at Magic Kingdom Park during the party. I recommend arriving to the event late afternoon, or early in the evening. You'll find that attraction lines are often much shorter than usual, making the evening quite magical!
Did You Know? The oh-so-jolly Mickey's Once Upon a Christmastime Parade features giant toy soldiers marching down Main Street U.S.A. There is fantastic live entertainment throughout the entire evening while complementary holiday treats are being served.
I hope this was helpful information, Kelsey. If you have any other questions, please come back to visit us again.
Ritzy ºOº
