The 2,394-passenger Norwegian Gem feels small compared to newer Norwegian Cruise Line ships, but this older vessel remains popular because of its intimate atmosphere and fun vibe. The ship perfectly represents what NCL fans love about the line's Freestyle Cruising, which offers flexibility as well as lots of choices for where to eat or drink (including 14 bars and lounges). Recent refurbishments have upgraded the decor in many of the common spaces, including the pool area, but some inside cabins are arguably a bit too snug at 138 square feet. Conversely, the 3-Bedroom Garden Villas in The Haven, NCL’s exclusive “ship within a ship” enclave, are a sprawling 4,252 square feet.
