Hi, Misty!
Welcome to the Disney Parks Moms Panel!
Currently, admission to all Walt Disney World theme parks is on a daily basis. Each ticket purchased can only be used for one day.
For example, if you entered the Magic Kingdom at 4 pm to see
Happily Ever After Fireworks show and to enjoy the magic of a few attractions during the night time hours until the park closes, you are free to enjoy the park for the remainder of that day. That same ticket can not grant you access to re-enter the park the next day, once the Magic Kingdom re-opens. An additional ticket would need to be purchased to visit the Magic Kingdom on the next day.
Enjoy your upcoming magical vacation!
If you have more questions before your arrival later this month, please visit with us again!
