As the sister ship to 2017’s MSC Seaside, this 4,132-passenger, family-friendly mega-ship from Europe-based MSC Cruises debuted in 2018 with most of the same onboard concepts and experiences to entertain and appeal to adults and kids alike. Its public spaces are designed to dazzle, with glittering Swarovski staircases and glass-floored “Bridge of Sighs” catwalk ideal for glam selfies and Formula 1 Racing simulators, a 5D theater, spiraling waterslides and the longest zip line at sea to thrill tweens and teens. MSC Seaview also features four pools and 13 hot tubs, 19 bars and lounges, and cabins and suites to suit most budgets. The ship sails the Mediterranean in summer and the Caribbean and Bahamas in winter, and its passenger base is significantly more international than most U.S.-based cruise lines. There is a lot to love on this big ship—if you love big ships, that is.
