Royal Caribbean International will offer a special seven-night sailing aboard the Oasis of the Seas this summer for guests to witness the total solar eclipse on August 21.

The company said: “The Total Eclipse Cruise will feature a bucket-list-worthy viewing party with a live concert performed by a major headliner – to be revealed at a later date – to celebrate the celestial phenomenon that is poised to become the most photographed, most shared and most tweeted event in human history.”

“We’re set to take vacationers on an unprecedented experience that is nearly a century in the making,” said Michael Bayley, President and CEO, Royal Caribbean International. “A total solar eclipse hasn’t crossed the entire U.S. since 1918, and with many of our ships sailing the Caribbean along the projected path, the stars aligned. Oasis of the Seas will have the vantage point of the century and an unforgettable celebration out at sea that adventurers won’t want to miss.”

The optimal viewing area along the eclipse’s path stretches across the country from Oregon to South Carolina before passing over the Caribbean Sea, according to Royal Caribbean.

On this trajectory, the sun will be entirely covered by the moon, and a moment this unique deserves an equally impressive experience.

Guests on Oasis of the Seas will be treated to a full slate of eclipse-themed activities, including dance parties, trivia, enrichment lectures, interactive science fun for kids, and tasty cocktails and dishes with names like the Cosmic Cosmo, Planetary Punch and Moon Pie, ensuring the most memorable and adventurous way to commemorate the Great American Eclipse.

The 7-night Total Eclipse Cruise on board Oasis of the Seas will set sail on Aug. 20, 2017.

Seven other Royal Caribbean ships will be in the Caribbean during the total solar eclipse on Aug. 21.
