There are 3 familes going on the same trip. My family has been on one cruise before so we get to do our online check-in 90 days out while the other two families can't until 75 days out. Two questions: (1) Will I be able to do our reservation for Paolo and Remy for all three groups and (2) When I select my check-in time at the port, can they check-in with me at the same time? We are traveling together. Thanks!
