But on the more upscale lines, including Seabourn, Crystal, and Cunard, you will that find people dress up for dinner. Some cruise lines even require men to don ties on informal nights. You can eat in a bistro rather than in the dining room if you aren't in the mood for formalwear. Generally it means a tux or dark suit for men, and a nice dress or pantsuit for women. I came down to dinner dressed to the nines, only to discover my tablemate's idea of formal was a polo shirt and slacks.
Most ships adhere to a strict rule that bans T-shirts and shorts in dining rooms at night.
You needn't don a tux to meet the captain, but be aware that shipboard etiquette deems it appropriate to show respect by looking neat. Also, don't miss Fran Golden's column on Barge Cruises . All rights reserved.
