The quality of the service by Victor and Flynn in the Main Dining Room was excellent and the best part of our cruise on the Navigator of the Seas. The overall quality of the service and experience provided by Royal Caribbean has slipped substantially from the service provided on a 2013 cruise to the Baltic and St, Petersburg on the Brilliance of the Seas. Shore support personnel arrogantly and rudely ordered passengers to leave the cruise terminal and go to Southampton when the ship was delayed by bad weather on the previous cruise. No indoor seating was provided to passengers who chose to stay at the cruise terminal for the three hours it took to get the ship ready for us to board. The sliding glass door in our Royal Family Suite was so clouded by condensation that we could not enjoy the view from the stern of the ship and the couch in the living room was stained. One of the headline entertainers performed the same songs in the same order wearing the same outfit as she did when she performed on the Brilliance of the Seas in 2013. Waiters assigned to the Chops and Izumi specialty restaurants frequently interrupted our dinners in the Main Dining Room to pitch reservations for their restaurants with intrusiveness that would shame a carnival worker, telemarketer or car sales representative. The Royal Caribbean excursion to the City Sites of Genoa toured the financial district at length but ignored the memorial to Christopher Columbus and omitted any discussion of his history in Genoa and his contribution to the exploration of the New World. As a final insult, Royal Caribbean has taken 34 days and counting to process a refund for part of our reservation to my credit card, despite repeatedly assuring my travel agent and me that it would take only 7-10 working days, and no staff level or managerial employee in Customer Service or the Crown and Anchor Society work groups apparently have the authority to call Royal Caribbean Accounting to expedite a refund that has been delayed by their errors.
