We just returned from the Grand Hawaii cruise. This was our first Princess cruise (cruised multiple times with other lines) so I don't have any other Princess ships to compare it to, but here are my thoughts.
Yes, it just came back from drydock, but she is still old and it shows. Rusty areas on the balcony, leaks every day in different areas, peeling ceiling tiles in the dining rooms from apparent leaks, old fixtures in the stateroom. We had no hot water in our stateroom shower for 2 days.
That being said, with the exception of a blase guest services desk and a poorly handled issue with a shore excursion, the service on this ship was amazing. Embarkation was a breeze, onboarding and having lunch in less than an hour from curbside to dining room. Our luggage was waiting outside our stateroom by 1:00.
All this to say, while it did have a lot of positives, I probably wouldn't do this ship again.
