It just got more expensive for on-site guests who travel with a vehicle…starting with reservations made March 21st, 2018 and thereafter, guests staying at a WDW resort and will have a vehicle parked overnight will now pay a self-parking fee, which will be added to their folio on check-out. The fee depends on the level of resort: $13/night for value, $19/night for moderate, and $24/night for deluxe including Deluxe Villa resorts. However, DVC members will NOT have to pay a parking fee when staying at a DVC Deluxe Villa, even if they paid points instead of cash.
The fee also does not apply to guests staying at campsites at Disney’s Fort Wilderness Resort.
