Hello Bettina!
I can tell that you are getting excited as you plan your
Magic Kingdom Park day!
Yes, with a standard or base
Walt Disney World ticket (in your case, a 1-day park ticket), you can leave the park and return to the same park later that day. There are only a few days during the year (typically the Christmas holiday and the days around it) where a park will reach capacity and limit entry into that park. There is no charge for returning to a park on the same day.
Keep in mind that currently, you will need to make a theme park reservation for each day of your ticket. To reserve your first theme park of the day, you will have to do a couple of things:
1. Make sure your Walt Disney World Tickets are linked to your
My Disney Experience Account2. Check the
Park availability for the first park you want to start in on that particular day
3. Make a
Theme Park Reservation for your first park of the day for each day of your tickets
I hope that your next Walt Disney World day is incredible!
