Best for: Entertainment enthusiasts
Why: All Norwegian ships offer musical revues, comedy and improv shows, live music and guest performers, but the line really shines with its newest ships: Norwegian Bliss, Norwegian Escape, Norwegian Epic, Norwegian Breakaway and Norwegian Getaway. The line takes its inspiration from land-based hits, and cruisers can experience Broadway musicals like "Jersey Boys," "Rock of Ages," "After Midnight" or "Million Dollar Quartet"; sizzling dance shows like "Burn the Floor"; comedy by Second City improv or Levity Comedy; and music by dueling pianists and blues bands. The line even turns meals into theater with dinner show Cirque Dreams. Throw in plenty of bars, discos, bowling and Wii, and you will never be bored onboard.
Runner-up: Royal Caribbean is also on the cutting edge of onboard spectaculars. The line features Broadway shows ("Grease," "Mamma Mia!"), but takes performances out of the theater with ice-skating shows in onboard rinks, high-diving acrobatic shows at the pool-based AquaTheater and aerial shows in ship atriums. Anthem of the Seas features the high-tech entertainment venue Two70, which pairs floor-to-ceiling windows of digital screens and six large "roboscreens" with live dancers, singers, aerialists and musicians. It also hosts a cast of cover bands and Dreamworks characters for family-focused fun.
