We are going out of Charleston so I think it unlikely that they print cards a the counter. Still a very new port for this stuff. I've been thru before and I think they separate from the first door into the terminal. So our friends will probably go through the regular line. It was pretty quick last time. I waited longer to park the car then to sign on the ship as I recall.
We plan to have lunch with the kids in Charleston and then board later than normal this time. So we can just send the others along early and meet them on board.
Thanks for all the suggestions. :)
