Here is my issue:
I have an AP and a 3 day trip scheduled in November and a 5 day trip from 12/27-1/1.
I booked FP+ for the 3 days of the November trip a few weeks ago, and when the window opened up for the December trip yesterday, I tried to book FP+ reservations for all 5 days for both me and my daughter who will be with me.
When I got to the 5th day, the system would not allow me to make FP+ because I had exceeded the limit, but it did allow my daughter to make them. Just out of curiosity, I cancelled the reservations for the last day of the November trip because I'm not sure exactly what we will be doing that day. After I did that, I was able to copy the FP+ reservations that my daughter had to my account for 12/31.
If I go back to try to make reservations for the day in November, it shows that I have reached my limit.
There does seem to be a 7 day limit on FP+ reservations for AP holders, or maybe it is just for
DVC AP holders, which we are. If that is the restriction for now., I can live with it because it is only an issue if you have a couple of visits in a 60 day period.
I still have an issue with some of the reservations that I made not appearing correctly on the My Reservations page. On one day, My Reservations shows just one FP+ reservation for just one of us. But if I try to cancel or change that one, the change screen shows 3 reservations for both of us at the times that I selected. My inclination is to just leave those and hope they eventually show up on the My Reservations list.
I like the concept of FP+, especially for travel at busy times, but this system is frustrating right now. Hopefully they will be able to work out the bugs.
