They asked you to be there an hour early and truthfully you should be you do have to sign in and you're given a page box that will light up and you go get your tickets then and how early you're in there is how quickly you go on
You don't want to be the last one, first come first seated. You sign in. You would end up sitting in the hottest part of the boat and be miserable
It was 6pm I believe for the day we went. They board in the order of checkin. So, last ones there are last to get on.
