When your FP Booking window opens for Stay#1, you’ll be able to book for Stay#1’s Length of Stay - this includes the first day of Stay#2 (offsite).
For the rest of the offsite Stay#2, you’ll be able to book 60 days out from each park day.
For the last day of Stay#2, you’ll also be able to book for the onsite Stay#3’s Length of Stay.
You don’t have to book daily for Stay#2; you can just wait until you are 61 days out from Stay#3 and complete all the FP Booking for the offsite days + the last 2 onsite days.
And,
to DIS!!
Thank you!
