I will preface this post by telling you that we have done 10+ cruises but not in about 10 years. We were used to the old style of cruising when men had to wear long pants in the dining room (or be turned away) and on formal nights, a suit and tie and I wore a fancy dress. From what I have been reading from recent reviews and posts on this board for the Mariner, it seems that men can now wear shorts at dinner and won't be turned away at the door. And when I say shorts, I mean nice dress shorts with a collared shirt, not gym shorts and a t-shirt! However, if this is not correct, please do tell me. We are a group of 18 family members and I have become the organizer so I want to tell everyone what they should be packing. Thank you!
