Resort-casual attire is recommended both on the ships and ashore. For dinner, men’s clothing might include sport shirt and slacks. Jackets for men are optional, not required. Women may wear a blouse or sweater and slacks, skirts and dresses. No shorts or hats are permitted in the dining room for dinner. American Queen Voyages also recommends that you bring comfortable walking shoes, a hat, light rainwear, an umbrella and a jacket or sweater for cool temperatures.
