Hi Travis!
Walt Disney World is so festive during the holidays! The parks are decked with zillions of twinkling lights, thousands of bright red poinsettias, and hundreds of brilliantly decorated Christmas trees. I adore the Mickey shaped wreaths that adorn the lampposts.
Travis,
standard theme park tickets grant you admission to any of the
four theme parks, but you do need a
Disney Park Pass Reservation and valid admission to enter a park. If you already have a park reservation for the Magic Kingdom for December 24th, you are good to go. According to the
theme park availability calendar, the
Magic Kingdom is currently full for this date, so right now booking for the day before Christmas in the Magic Kingdom is not possible unless more openings become available.
If you don't have a park reservation for Christmas Eve day, I recommend making a reservation for one of the other three parks quickly. Maybe with some pixie dusted wishes, Magic Kingdom spots will open at a later date. Do not delay booking your park dates; Christmas break is a highly popular time at Walt Disney World.
Wishing you the very merriest visit to see Mickey!
Elisabeth
