None of the WDW
DVC resorts have additional fees at check in when booking with points. Aulani and some of the
Disneyland DVC properties do.
I follow DVC's cancellation rules:
31 days or more before check in: no restriction on points, they're good through the end of the use year. In this case your points would be good through September 2025 and I would help you rebook.
30 days to 1 day prior to check in: Points are placed in a holding account. Points would still be good through September 2025, but I cannot book out further than 60 days in advance.
Day of check in: Points are forfeited.
Once you have 10 posts it takes the system 24 hours to grant you access to the PM system.
