Royal Caribbean International today announced that the musical Grease will take the stage onboard Harmony of the Seas and Independence of the Seas.

“Grease is a show that speaks to families of all ages and is sure to get guests out of their seats, singing and dancing, which is why we made the unprecedented decision to have it debut on Harmony andpremiere it onboard Independence immediately, starting in July,” said Nick Weir, Vice President, Entertainment, Royal Caribbean International. “As the first cruise line to bring Broadway performances onboard its ships, it’s only fitting that we would also be the first to bring Grease to the hospitality industry.”
