There are ALWAYS some that want to dress up, there are always some who are TOO casual and then there is the LCT bunch that gets it JUST RIGHT. Dress for dinner is not important you will see the same basic things I always wear on a ship. Chico black pants and a few tops I will repeat a couple or three times. Do bring some lighter weight items they can make it HOT on the ship over compensating for the cold outside. I can assure you Ken will NOT have a coat and tie.
