A lively Mediterranean spirit and modern décor set the decidedly European tone of 3,502-guest MSC Preziosa (meaning "precious" in Italian). For passengers who swoon over sparkles, this ship from MSC Cruises amply satisfies with grand, Swarovski-crystal-studded staircases, Murano glass, white marble, and opulent sculptures everywhere. It’s almost surprising this level of panache can be paired with bargain fares. More well-heeled cruisers can upgrade to the Yacht Club, a ship-within-a-ship enclave, which encompasses 69 suites with butler and concierge services, plus a private dining room, lounge, and pool. It even has its own signature fig-and-almond scent wafting in the air, which is subtle yet inviting.
