We enjoyed this cruise greatly. The Diamond Princess staff was excellent and the room steward was the best we've had in 10 cruises we've taken. It stormed the whole time we crossed the Bering Sea with high seas and high winds for 5 days. The ship was amazing in that it was fairly stable the whole time and I never lurched into a wall while walking which we have done on cruises venues that included Cabo San Lucas to Los Angeles.
While a cough developed on board the staff kept railings sanitized well. (you could smell it) There's no accounting for people though and their rudeness in going out and sharing something that is going around surprises me. Rude passengers is not Princess' fault though.
We enjoyed the dining and the entertainment. Entertainment can be repetitive when you cruise frequently with the same cruise line and the Diamond was no different although the quality was high caliber. The only negatives were that this ship's does not have the International Cafe of the caliber of the Sapphire's and the Sterling Grill was in the back portion of the Horizon Court making the ambiance poor. We had planned a night in the Sterling Grill but when we saw the environment we changed plans and stayed in the dining room. Service varied highly from dining room to dining room. We found our niche though and even had servers ask for us to be seated in their section.
Positive experiences with Princess keep us coming back.
