From the embarkation chaos in the Cruise Terminal to some of the poorly trained staff, this was the absolute worse Princess cruise I have ever experienced it 25 years. No designated queues for check in, such as for “Elite and Platinum level” were displayed. Discussions with fellow Elite level cruisers support my negative experience with this sailing. In fact, Princess Cruises awarded every guess $100 on-board credit to try and appease the dissatisfied passengers after our disorganized, chaotic embarkation day. This ship should have been refitted after the Summer China cruise season, instead of waiting until next March, 2018,as it has become dated and detoriated. Some of my fellow passengers experienced food-poisoning like myself, in discussions during the final days of our cruise. My illness came from the Trident Grill when an inexperienced Chinese cook, grilled a cheese burger for me. Within 3 hours I was vomiting and experiencing diarrhea. After reporting this occurrence, I was isolated to my room until 24 hours after the diarrhea ceased. Difficulties understanding public address announcements were normal, as the young lady once told me jokingly, that she spoke “Chinglish”. Our table mates quit dining with us in the Dining Room, after their numerous, poorly cooked main courses were returned to the kitchen on the first 4 of 5 evenings. They were totally disgusted with the food and never returned to the Dining Room. The staff overall, tried their best and were to be commended for their attitudes, but Princess Cruises must revise their Dining programs, as well as other areas of the cruise experience.
