Because they have a package, their tickets do not become “valid” until their 60 day window.
But you can book for them when their window opens, so for that week you can all be together. Unless of course you go ahead and book some FPs like FoP for you for that second week. Then just try and get overlapping times.
You shouldn’t have problems with your FPs, but if you do call the AP Guest Services line. Sometimes AP holders have issues booking FPs for all of their onsite stays, but the CMs at the AP desk can help. It usually only affects split stays or those at the DS resorts.
