FP+ lead time?

[wjdoc]

So I may not purchase my park hopper passes for my trip apr 26th until about a month ahead if my trip. A local charity will have them at a silent auction, so I figure I can help them out since I need them anyway. My worry is: Will I be locked out of tsm and soarin altogether if I wait that long? Or will I be stuck with 11pm or some time that makes no sense for me?

We couldn't link our tickets until we arrived. I was still able to get everything I wanted two days before...
