Our 16 day cruise from 11-18-07 to 12-3-07 on the Diamond Princess was quite a disappointment. This was our 8th cruise (4th with Princess) and this was the worst one. Two days into our cruise we came down with the Norovirus and spent 7 days confined to our stateroom by the ships medical department. We later found that many others caught this Norovirus as well. We were told that if we were caught outside of our stateroom the first time we would be escorted back. The second time we would be put off the ship at the next port. But we were to sick to even think about leaving the room. That meant no cabin service to clean the room and if you felt like eating, very limited lite diet food from room service. We missed the first three port calls in Hawaii and our shore excursions. After improving health wise and being allowed to leave the cabin we found the food in the dinning room to be the worst we have ever experienced on a cruise ship. The Horizon Buffet was not much better. We also found dried food on clean plates and silverware. We were given dirty glasses with lipstick prints. We spent many of our lunch and dinners eating from the hamburger bar near the pool. We found that many other passengers were eating there as well because of the terrible food the both the dinning room and the buffet. We also experienced many rude employees in the dinning rooms, in the buffet area and at the purser's desk. We missed half of the shows due to sickness. We missed others because there were no seats available. Of the shows we did see, many were very poor quality of entertainment. Several of the public restrooms had a bad smell and were not clean. We stayed away from them and used our stateroom. This was our 4th cruise with Princess and we have been extremely happy with past cruises, but they really missed the boat on this cruise. The stateroom was nice. The ship was beautiful but it was very obvious the service was lacking for the amount of passengers unless you ordered drinks. There seemed to be an endless amount of bar waiters. The Debarkation process was a nightmare due to a bomb threat that delayed everything for two and a half hours.
