This was a transatlantic cruise. We have cruised Silver Seas, Holland America and Carnival in the past and thought we'd compare HA with Celebrity. The rooms and overall ship décor are more appealing on Celebrity. Service was good but the overall communication was deficient. For example, we'd ask a question and the customer relations gave information that was often not correct. This was also apparent with other departments. The same menu was repeated over and over, no diversity-especially the buffet and Luminae Restaurant. The informational sessions were lacking and the offerings on ports of call were nothing but a sell, sell, sell! HA port informational sessions at least give you valuable information about the ports and some history as well. We were very disappointed. Entertainment was good. For as big as the ship is there is only one complete deck to walk around and that was ALWAYS crowded unless we went out during bad weather or late at night. There is an open deck but it doesn't go completely around the ship. Everywhere we went was crowded. One of the shore excursions, Le Harve, France was not worth the money-we docked on a national holiday and most stores, restaurants were closed and the tour guide finished her supposed to be 2 hour tour, 2 hour on your own according to the brochure descriptions in 45 minutes and left everyone to see Le Harve (again national holiday) to walk around for 3 hours! Be aware that they tack on 18% gratuity to the price of everything you do on the cruise (specialty restaurants, spa, etc) that is over and above what is included is automatic-you don't have a choice in what you tip. We won't be booking another Celebrity cruise again.
