2016 marks 50 years since the Sunward made her first voyage from Miami to the Caribbean on December 19, 1966, which was the start of Norwegian Caribbean Lines.

To celebrate Norwegian is inviting its guests, travel professionals, partners and team members to share fifty years of memories made through the company’s #NorwegiansFirst50 Anniversary Campaign, according to a statement.

“We are celebrating fifty years of incredible moments aboard our ships and it’s the people — our guests, travel partners, team and crew members — who make our history so special.  We wouldn’t be here today without their loyalty and dedication,” said Andy Stuart, President and Chief Executive Officer for Norwegian Cruise Line. “We invite everyone who has sailed with us, commemorated a special occasion with us or made memories onboard to share their favorite moments and celebrate our first fifty years along with us.”

Through the global initiative, Norwegian Cruise Line guests, travel partners, and current and former employees are invited to upload their photos and stories to NorwegiansFirst50.com.

Fans who upload memorable moments to the site, which will serve as a living, growing tribute to 50 years of feeling free out on the water, are encouraged to share their memories with friends on their social networks, with the chance of winning a free cruise as a reward for joining in the celebration (in participating markets).
