These 6 Luxury Cruise Lines Have the Most Over-the-top Suites at Sea — With Ocean-view Saunas and Private Plunge Pools

"Staterooms on the newest ships emphasize a residential sensibility, arriving with foyers and powder rooms that enhance privacy and flow; many accommodations feature walk-in closets, hot tubs, double vanities, and personalized mini-bars. Among the most spacious options, the Grand suites offer massive wraparound balconies with lounge chairs that look over the bow, while the line's Silver suites greet guests with generous lounge areas designed for relaxed, upscale living aboard ship." - Janice Wald Henderson
