My husband and I are going on an Alaskan cruise on the Carnival Spirit in May 2007. What type of attire do people wear on non-formal nights in the dining room? I have only cruised Carribean and wear sundresses to dinner on non-formal nights. I was thinking of wearing nice slacks and pretty sweaters or blouses. My husband I'm sure will wear slacks and nice polo type shirt (short sleeve as he is always warm). Any advice would be appreciated. Thanks so much.
