Are they strict about reservation times? Has anyone been able to enter before their pre-booked time? We made reservations for 11am, thinking we can realistically get there between 10:30-11am. I read online you could be denied if you arrived after 30 min into your slot, so just curious if they are lenient about letting people in early if its not crowded.

I’m trying to make a reservation but the website stalls on the payment page. I tried 6 times in the last 2 days. Is there a problem? Does anybody know when it will be fixed? For reference this is the website I’m using gostateparks.hawaii.gov/diamondhead
