Sail Norwegian Cruise Lines For Affordable Fun. Norwegian Cruise Lines is the top choice for families seeking exceptional dining at sea, and top rated entertainments. The Breakaway Class of ships sport multi-story waterslides, including the adventurous Free Fall. If that’s too much, there’s always a hot tub waiting to be filled or the thermal suite at the spa. After dark, hit a steamy Broadway-style show, such as Burn the Floor or the Tony-nominated Rock of Ages. Traveling without the kids? Escape to Spice H20, Norwegian’s adults-only, top deck getaway. Then there’s pure dinner theater with acrobatics in Cirque Dreams or the magic of Illusionarium. With Norwegian, you’re not held to strict dining times in the same restaurant every night and you can dress casually. That’s the come-as-you-are appeal of Norwegian Cruise Lines. If non-stop entertainment and the thrill of dining somewhere new each night sounds great, push off to your next destination with Norwegian.
