Hi Lacee,
Thanks for bringing your question to planDisney! I'm happy to help make sure you're tech-ready for your upcoming visit.
Yes, you can modify your
Lightning Lane Multi Pass purchase to another park, subject to availability, using your
My Disney Experience App. Click the three horizontal lines at the bottom right of your app screen, then select the tile for Lightning Lane Passes at the top right. Select the existing Multi Pass selection you'd like to change, then follow the prompts to "Modify Lightning Lane Pass." Confirm the members of your travel party, then choose a new date and/or park on the following screen, and continue to make your new attraction selections. Though this modification can occur up until the moment you redeem your first Multi Pass experience, I recommend modifying as soon as possible, as return window availability may be limited this close to your travel dates. Keep in mind that you'll need to pay any difference in price should your new park be more expensive, but refunds will not be issued even if your modified park is less expensive.
I suggest walking through a new purchase process for
EPCOT first to review what attractions and time slots are available before making modifications to your current plans. You'll be able to review current options before finalizing the transaction, and though availability can change within the time you view and attempt to modify, it will give you a good idea of your options at EPCOT that day. You can also choose to keep your current
Magic Kingdom Park selections and try modifying the times to later in the day. That way, you can start at EPCOT and have a full afternoon of fun waiting to be redeemed once you hop over to Magic Kingdom.
I hope that helps, Lacee. Please come back and see us again if you need further clarification. Wishing you a wonderful vacation!
Magic and memories,
Amy
