Do you need to check in at FP+ for it to count?

I thought after your initial 3 fast passes that you could only book one at a time for each additional one.

If you haven’t booked a total of 3 as your “initial 3,” you can book day of for another park after using 1 FP.

@hiroMYhero is--as always!--correct. I just did this on a recent trip--had 1 FP+ booked in HS (for TSMM) and as soon as we got off, I booked a FP+ for FoP. Shocked me that this worked! But thrilled that it did. And the FP+ was for about an hour after I booked it, giving us plenty of time to bus over to AK and enjoy FoP!

I like to tap out the 3rd one if I really want a chance to get a tier 1 fourth FP.
.............and I do it 5 minutes early.....its allowed!
