On a 7n cruise there are typically 2 formal nights, 1 informal and 4 casual nights. No jeans allowed in the dining room any night
One or two a week but not every night, smart casual or informal other nights, but definitely no shorts or jeans and you can always dine (or eat) in the Windjammer or Rockies if you dont like dressing u.
If you are dining in the main dining rooms then there are three types of evenings, one is CASUAL, the second is INFORMAL and the third FORMAL. CASUAL dress is as you would expect but no jeans, tee shirts or football shirts and no shorts. INFORMAL dress is a jacket and tie for men and something more dressy than casual for ladies and FORMAL is normally DJs or tuxedos or a suit for men and a cocktail or long dress or a nice combination for ladies. You can avoid dressing in the latter two if you wish by dining in the Windjammer where a reasonable casual style is accepted. People do tend to follow these styles almost as much as they do on Celebrity, their sister company. You will find more details in the brochure or on their web pages…..hope that helps…….Ida.
