There's been a lot of speculation around this port arrival time. Some people still just show like regular time and will sometimes receive their boarding number which could be low or high. There have been stories of people being handed a five or six and then when actually checking in the CM would change it down to a two or three, etc. I think the boarding times are to try to stagger people as much as possible. Once you are there, you will receive a boarding pass number. This is what they call to get on the ship and is what is important. If you have a three and your family has a ten, DCL allows the entire group to board on the lowest number called. So you will all be able to be together.
Thanks for the info, good to know!
