What happens to my FP+ if I decide to use my tickets a couple days early?

[allysetraskos]

So we booked 8 Days at CBR with 7 Days of park tickets...
However we found out we may leave early now and stay at AOA for 3 days...
We read that you can use your park tickets that are part of a package up to 3 days before check-in by going to guest relations.
We want to use 2 of our park tickets while we are at AOA prior to checking into CBR.
I just want to make sure that it dosn't mess with my FP+ choices, Has anyone done this before? Would I just make FP+ selections for 5 days and leave the other 2 empty? / would the system know to take from the empty days?

Just add two more days to your tickets at the park Guest Relations sometime after you enter that first day.
(Or, add the days to your tickets when you go to Guest Relations to activate your tickets early.)

You'll be able to keep your original FP+ choices on the days you have already booked.
