Good morning! My family is taking a cruise in the next couple months. DD and I will be driving and DH will be flying. DD and I would be able to get to the ship first thing in the morning, while DH will likely not get there until lunchtime. My question is whether DD and I can check in and board the ship earlier than DH? If so, would I do his check-in for him or would he do that on his own when he arrives? Thanks!
