Seven Seas Mariner from Regent cruises is the world's first all-suite, all-balcony ship, as well as the first to offer dining by the famed Le Cordon Bleu of Paris in Signatures, one of four single, open-seating restaurants. Catering to only 700 guests, this luxurious Regent cruise vessel is one of the most spacious ships afloat, and, her staff to guest ratio of 1 to 1.6 provides the highest level of personal service.
