Welcome to planDisney, Shannon. Thanks for stopping by with your question for us.
If you wish to switch your park reservation day to a different one, you can definitely do so, provided that: 1) the dates are in the same tier for your one-day
ticket (or the new date is in a lower tier), and 2) there are park reservations still available. It looks like both dates you mentioned are Tier 5 tickets, so you shouldn’t have issues switching from 9/4 to 9/5/21. Your next step is selecting the park. Before you change your reservation, be sure to check out the
Theme Park Reservation Availability calendar to see which park is available on the day you wish to visit.
In order to switch your visit days, you’ll actually need to cancel your current park reservation for 9/4/21. Then, return to the “
Theme Park Tickets & Reservations” page and under “If you’ve already purchased a ticket:”, click on “Make Park Reservations”. Pick the date and park you wish to visit and confirm your selections. Once your new reservation is processed, you’ll receive a confirmation email.
I hope this information is helpful for you. Please don’t hesitate to
write us again if you have more trip-planning questions. Be sure to visit

Have a magical day,
