In celebration of the Harmony of the Seas' European debut, and in anticipation of her U.S. arrival in November, Royal Caribbean is kicking off a multi-faceted consumer promotion, “Ticket to Adventure.”

The immersive and interactive sweepstakes encourages consumers to virtually discover and explore Harmony’s thrilling features and seven neighborhoods, and enter for their chance to win more than $300,000 worth of prizes that range from a grand prize, seven-night Caribbean cruise for four, to 200 invitation-only getaways, more than 175 GoPro HERO4 cameras, over $40,000 in gift cards, and more.

Starting April 21 through November 5, 2016, consumers can simply register for the promotion at RoyalCaribbean.com/TicketToAdventure, and then the adventure begins!

Every two weeks, one of Harmony’s seven signature neighborhoods will be unlocked on the site and open the door to interactive content and fun facts, such as the height of The Ultimate Abyss, the tallest slide at sea, to the number of plants in Central Park – the largest living park at sea – and the variety of cocktails the robot bartenders at Bionic Bar can sling.

Bonus instant win games are hidden within each neighborhood and extra sweepstakes entries will be awarded to those that share Ticket to Adventure with their friends via email or social media.

There will also be other ways to enter the contest, as Royal Caribbean will infuse a little adventure into some unexpected places and pop culture events, as well as partner with well-known personalities.

Actor and singer Carlos PenaVega will give fans the chance to join him onboard Harmony of the Seas during exclusive, invitation-only preview events in Southampton, England. Hot off his starring role as Kenickie in FOX’s GREASE LIVE, PenaVega will hang out with his winning fans as he leads a number of Grease-inspired special activities and attends opening night of Royal Caribbean’s original production of Broadway’s hit musical Grease. Fans can enter for the chance to win by visiting the sweepstakes site between now and May 1 and entering code GREASE.

 In addition, Royal Caribbean will deploy a series of code words that can be uncovered on RoyalCaribbean.com, through Royal Caribbean emails and exclusive Crown & Anchor Society newsletters for loyal guests, as well as through participating travel agents, or by following Royal Caribbean on Facebook, Twitter and Instagram. Consumers that find a code can enter it at RoyalCaribbean.com/TicketToAdventure to be entered into the grand prize drawing and also to unlock chances for instant win prizes.

Delivery of Harmony of the Seas to Royal Caribbean is scheduled for May 12, with departure to Southampton, UK around May 15.

The next set of sea trials is scheduled to be held before the end of April.
