Royal Caribbean International has decided not to install its Dynamic Dining concept on the Oasis, Allure and Harmony of the Seas, as it once planned to do.

The concept, which splits the main dining room into four smaller themed restaurants, will be limited to ships that have been designed from the beginning to accommodate it, Royal said in a statement.

Currently, the Quantum class ships, including the Quantum of the Seas and Anthem of the Seas, are the only ones predesigned for Dynamic Dining.

Dynamic Dining originally also meant elimination of fixed dining times, but Royal later added a “classic” option with early and late seatings.

Royal had already converted the main three-deck dining area on Oasis of the Seas into single restaurant spaces on each floor.

Guests on the Oasis, Allure or Harmony who have already preselected the classic option for their upcoming cruise will be assigned to either early or late seating to match their original choice of time. Guests who have selected the “choice” option will be assigned to the My Time Dining program, Royal said.
