We are sailing to Alaska this summer with me, DH, DD6, DS4, my parents and in-laws, so 8 of us. We are Silver members, and got a PAT of 11:30. The grandparents are first time cruisers, so the earliest PAT they could get is 12:30. My question is, since we're all traveling together, would they be allowed to board on our boarding number? or should they wait another hour before coming to the port?
