A little. There's no dress code during the day -- comfortable, casual wear is the watchword. There are no formal nights, but people do dress up more smartly in the evening -- think sport shirt and slacks with a sport coat or sweater for men and resort wear (dresses, sweaters, slacks) for women. On the final evening, men generally wear a sport coat and tie and women wear a dress.

No. Fares include meals, wine and beer with lunch and dinner, and all excursions. Bar drinks and gratuities are not included.

The emphasis for St. Lawrence Cruise Lines passengers is on slow-paced, educational touring, that is to say scenic sailing interspersed by informative shore tours -- mainly gentle walks around places of interest. Generally, St. Lawrence Cruise Lines attracts more sedentary passengers and activities onboard reflect that. Shuffleboard and trivia games are highlights of onboard entertainment, and there is low-key entertainment in the grand salon in the evening.
