Usually they will let you board if the ship is ready......Rooms, food, and all the passengers are off the ship....I've been able to board on a few ships around 11:30, but that was unusual...They have such a short time span to get it ready for oncoming passengers....I guess you would have to show up early and hope:-)
But no matter what, you will get on the ship.
Happy sailing...
