While Walt Disney World Resort Hotel Guests (and those at the Swan and Dolphin) have been able to book FastPass + reservations for 60 days prior to their visit, it now seems that Disney will roll-out the same benefit to multiple Walt Disney World Good Neighbor Hotels, including those on Hotel Plaza Boulevard near Disney Springs.
While a complete list is not available as of yet, we know that these non-Disney hotels will be able to offer their guests the 60-day FastPass booking window sometime before the end of 2017. These bookings will still be done through the MyDisneyExperience app, the same way other resort guests make the advance FastPass+ reservations.
We expect every hotel in the Disney Springs Resort Area on Hotel Plaza Boulevard to be included, but there should also be additional Good Neighbor Hotels on the list when announced by Disney.
Walt Disney World Annual Passholders and all other guests with linked tickets receive a 30-day booking window currently.
