Norwegian Cruise Line has announced that they will launch a "kids sail free" promotion. USA Today reported that they are the second cruise line this month to launch this promotion. The cruise line based out of Miami said that families that book select cruises by this Saturday can bring two children ages 17 and younger for free. Rules include that the kids must stay in the same cabin as the parents.

"Sailings to Alaska, the Bahamas, Bermuda, Canada/New England, the Caribbean, Europe and Hawaii are included in the offer," reported USA Today.

Parents are also eligible for a free balcony upgrade and $1,000 in air credits, reports USA Today. Crystal Cruises offered a similar promotion earlier this month.

In addition to having their kids sail free, parents booking select voyages also are eligible for free balcony upgrades and up to $1,000 in air credits.

"The ultimate family vacation just got better! Do the things you want, when you want. That's the freedom and flexibility you have with Freestyle Cruising on Norwegian Cruise Line," said Norwegian Cruise Line's website. "Unpack once and visit multiple, exotic destinations with ease. And with your accommodations, dining options, family activities and exclusive entertainment with Nickelodeon all in one place, there's something for everyone."

Norwegian has Freestyle Cruising which is informal and laid back and includes a number of complimentary dining options.

"The freedom continues with entertainment for everybody. From Broadway shows, to adults-only clubs where you can dance 'til dawn, to supervised activities for kids and teens. When it's time to recover from the excitement, you can retreat to accommodations designed for the way you cruise," says Norwegian's website.

Freestyle Cruising also includes a number of room options for cruising. They offer 2-bedroom Family Suite rooms for bigger groups or full-size stylish studios for solo cruisers.

"We also have a large selection of Oceanview and Inside Staterooms to choose from. So you can find the right accommodations for whatever you have in mind," says Norwegian's website.
