We took Celebrity on what was to be our first Mediterranean adventure last fall. While the ship was basically nice, there were many problems that made the experience unpleasant and disappointing: "sewer" smells in the halllway, back ups in the shower, less-than-clean balcony furniture, wilted flowers, and definitely second-class cuisine. The personal service that we had enjoyed on two earlier Celebrity cruises was lacking in the dining room, and the constant hard sell of shore excursionsoften accompanied by warnings about personal safety if you put foot on shore without a Celebrity guidewere annoying and insulting. Added to this, lunches in the dining room were not served while in port (nearly every day), and the Summit ran out of everything from coffee cream to strawberries before the end of the cruise. Breakfast in the cafeteria was presented with boring repetition, almost exactly the same day after day. The quality of the entertainment varied, and there was nothing to do and little choice of food after 11 p.m. Celebrity has had problems with the propulsion system on this ship for years, and they have failed to solve them. They were engaged in a lawsuit, as I understand it, with the manufacturer, but they continue to use the propulsion system although it has repeatedly failed. Owing to this, we had to skip our port in Croatia. Also, we were scheduled to dock at Livorno/Florence, but the captain choose, because of the weather, to anchor at La Spezia. This forced us to use the leaking and ill-functioning ship's tenders into port. When we returned to La Spezia (after a 3-hour train ride in each direction to visit Florence), we were ordered to queue on the quay in a gale (winds of 50 mph) and cold thunderstorm, with water washing over our feet and tree boughs falling from above. There were no facilites, no bathrooms, and no shelter. Celebrity was unable to return us to the Summit, but their personnel warned us not to leave the quay. If we were not there when they were ready to board the tenders, we would be left behind. Following this experience, I had a cold that developed into a sinus infection requiring several courses of antibiotics, steroids, and finally, surgery. Celebrity did not offer as much as an apology, no less any other compensation.I consider Celebrity to be not just disappointing, but negligent. I will never, never travel with them again.
