We embarked on the Diamond Princess in Whittier, Alaska and sailed through Asia, ending in Bangkok, Thailand. The itinerary was wonderful and most of the shore excursions were expensive but pretty good. We particularly liked the "home visit" excursions, where we had a chance to meet the local people.
The ship was a little large for our liking and it seemed to be too large for the staff as well. We felt that there was an air of chaos on the ship. Part of the problem is that the Passenger Services staff didn't seem to know what was happening or know much about the ship. Most of the information we received from them was incorrect, one time causing us to almost miss a shore excursion. Calls to Passenger Services in the evening were often not answered or answered by someone who was not a Passenger Services staff member.
One thing which I really missed is that they didn't have a ship's newspaper. This is the only cruise I've ever been on that didn't have a newspaper available for passengers. The internet wasn't working for the better part of the cruise so we felt cut off from the world.
