If you cancel your reservation 30 days or more before the reservation date, Disney will refund the price for the reservation.
You will be refunded the amount paid, minus non-refundable purchases like runDisney race registrations and travel protection plans. But, there will also be a $200 cancellation fee.
Once you enter the 24-hour window leading up to your Walt Disney World resort reservation, the entire package and payment become non-refundable.
If you want to change anything within 30 days of the upcoming reservation, you may be subject to a $50 change fee.
