You are partly correct.I don't believe so. You can only make FP reservations at 60 days going out for the length of your stay, to my knowledge. You would have to wait until 30 days before the rest of your park visit days if you are staying off site. What I'm not sure of is whether your one night on property would enable you to make FPs at 60 days for both your arrival and checkout dates though.
I don't believe that is correct. It would be 30 days out rolling once the OP moves off property, not 60.You are partly correct.
You do indeed get length of stay for booking FPs. OP would be able to make FPs for both check-in and check-out day at 60 days out.
After that, there is a “rolling 60 day window”. So exactly 60 days out from each subsequent day, they can book FPs for that day. Until they run out of ticket days, or until the tickets run out.
What happens is that your onsite reservation opens the booking window at 60 days out.How odd if that's the case!
