I'm a relatively new cruiser: as of this writing I've only sailed twice: on the Jewel (June 2011) and the Gem (June 2012). Since I cruise solo and on a very tight budget, I was interested in the Breakaway because of the studio cabins "priced for the solo traveler, no single supplement required."
Through a huge stroke of luck, I was able to travel on the Breakaway on June 23, 2013. Though I wasn't able to book a Studio cabin (it cost more than the Guaranteed Inside!), I was delighted to be on board. I especially enjoy cruising because as a freelance journalist, it's the only way I can truly escape from my phone and my computer!
NCL was my first cruise line and I've returned over and over because my experiences have been flawless. The customer service and the food are EXCEPTIONAL in my opinion, and I have met many fabulous crew members and passengers alike. The same was the case on the Breakaway, and Bermuda was lovely. So my review is more about the design of the ship.
Corridors nice and wide on this deck, but there is an outward-opening cabin door plus a potentially dangerous pillar right smack in front of the cabin! Cabin storage does NOT include drawers. Theater noise bleeds through to the cabin.
