So let's say the FP+ for the family involve two rides that everyone will ride and one ride that everyone except grandma will ride. If I don't get a FP+ for grandma, will that affect our ability to book a 4th FP+ later on for the whole family? Would it be better to book it for her and let it expire? We will be park hopping too!!! So I thought no problem, it's still her 3rd FP+ so whatever, but we can't switch parks until she uses the 3 or they expire, right?
