This was our fifth cruise but the other 4 were much better.We found the food in the Horizon buffet, and in the Vivaldi dining room was not as good as on Celebrity,Royal Caribbean & Carnival. The shellfish was especially disappointing. Usually these cruise ships have one enormous dining room and have a violinist or pianist playing dinner music but on the Diamond Princess it was split into 5 smaller ones with piped music. We're used to receiving a docket or receipt with each purchase but we had to ask each time & for some staff it seemed too much trouble.(after 16 nights how can one remember how many drinks or bottles of wine were consumed); also on some cruises you can check your account on your stateroom TV but this wasn't available. The public toilets were below standard,particularly the one near the Internet room which had a urine smell detectable 30 meters away.It was mostly rectified a few days later. The gymnasium did not have enough equipment available & we gave up trying to get any in the mornings.The exercise bikes were locked in another room & were only to be used under supervision as "they were dangerous". Can't they supply safe exercise bikes like everyone else? The shore excursions were disappointing with guides who rushed us back before important activities(changing of the guard in Taiwan & a dance show in Okinawa).Actually the whole Okinawa trip & onshore tour was a waste of time. Also the bar on the 18th.Deck was a beautiful room with lovely views which we wanted to use for our pre-dinner drinks,but it was only open at night.Such a waste! At that hour it was difficult to get a seat in the atrium. Our ship was too large to get right into many ports & we used container terminals & had to travel more than 2 hours each way in some ports. On a positive note service was good; our cabin was good and the shows were excellent.
