My husband and I just got back from our Hawaii cruise this Monday. It was really wonderful. The Diamond Princess is a lovely ship and the staff is very personable and helpful.
We had an inside cabin. It was nice, but I think if I am on a ship for more 7 days I will get one with a window or balcony. The sea days are filled with a wide choice of activities from classes to lectures to demonstrations. Or you can do nothing at all!
We ate in all three of the open seating dining rooms and were very pleased with the food and service. Crisell in the Savoy Dining Room is especially nice. We did have a bout with the Norovirus two days out, but the response was swift and thorough. As a result, it only affected about 22 passengers (35 crew!) and the Captain kept us very well informed at all times.
