As Royal Caribbean International prepares for the inaugural sailing of the most advanced vessel in its Quantum class of ships — Anthem of the Seas — at the end of April, Encore Cruises has an exclusive offer: free prepaid gratuities on Nov. 10, 2015 through April 18, 2016 sailings on the ship. The offer is valid on all new bookings made between April 23 and May 31 and on the Anthem of the Seas on Caribbean and Bahamas sailings in any category. Encore Cruises will give prepaid gratuities to the first and second passenger. RCI will also offer a free upgrade from an oceanview stateroom to a balcony and a 50% reduced deposit. Anthem of the Seas’ inaugural Europe season has 19 cruises to the Spanish, French and Italian Rivieras, and the Canary Islands, on three- to 16-night itineraries. It will reposition in late October to Port Everglades in Fort Lauderdale from where it will sail five- to eight-night itineraries in the Caribbean through the winter season.
