They said if you arrive late they will honor your ticket and you'll go in whatever time slot they're on.
The FAQs say don't come early, don't come late come on your time. Do i would check it out with them without assuming it's ok.
I believe tickets are good for the time or after so you should be good 👍
U probably will have tl exchane the ticket. When I went they grouoed everyone according to their entry times so without the appropriate change it may lead to confusion or even denial of admission
