It's length of stay for an onsite reservation with an AP. We stay an average of 2 weeks so it's great to book all days @ 60 days out. There may be a limit of 7 or 10 days for the booking @ 60 days; but the days over that were rolling 60 days out.
With ONLY an AP, your onsite stay of 7 or more days
NOW prohibits you from making ANY days of FPs @ 30 days for an offsite stay.
YET if you have additional multi-tickets linked, you are allowed to book up to the 7 days.
Otherwise, you need to wait until you use one or more days of your onsite FPs until you have 6 or fewer days of FPs remaining,
then you may book the 1 or more days of offsite FP for a total of 7 days including the onsite days.
So you lose the 30-day booking privilege of multi/ticket users, with only being able to book @ 1-day ahead,
instead of the 30.
This places AP holders @ a disadvantage.
