So I live in Virginia and will be visiting WDW in June (staying on-site). Family members live in Fla. and have APs. Is there a way to coordinate our FP+s?
You can all "join" one account and that person can make all FP+ reservations.
It would have to be that a "common date" before the trip would need to re reached for FP+ booking.
Guests staying at a WDW resort can book up to 60 days in advance.
Then, the FL residents (if they are NOT staying at a WDW resort) could be booked
up to 30 days in advance.
If you book the WDW Resort guests first, when the 30-day date arrived, you could
try to COPY the existing FP+ times over to the non-WDW resort guests.
But, BTW, this can be difficult... to impossible (depending on the attraction, the timing, and well, everything.)
A very daunting task and one that you must be willing to spend a lot of your time trying to coordinate.
Another method is to wait until ALL guests will be within the 30-day window and try making the FP+ all at once. That will have its own set of advantages and drawbacks.
