Regent Seven Seas Cruises
Seven Seas Mariner
The casually chic, 700-passenger Mariner feels like a floating country club with a relaxed, upscale style that allows passengers to be themselves. By that I mean you can dress up or down (but no jeans at night), dine where and when you want and take advantage of all the free shore excursions or just plop on a chaise and read a book.
