FP+ Grace Period?

[jsrj21]

I'm wondering if I have a FP for let's say Pirates at 6:00pm....can I try to get on a few minutes prior to 6:00pm or does it have to be during the exact window, in this case 6:00-7:00pm?

Don't know if they have a grace period before or after the one-hour block.

Thanks!

You can be 5 minutes early and up to 15 minutes late as a general rule. ymmv.
