We have been on 13 cruises and spent 147 days at sea, we are Platinum members with Princess, this review is from our perspective and is based on our experiences on previous cruises we have done and the video and written marketing expectations created by Princess.
Embarkation was a disaster with people queued for 2.5 to 5 hours in the heat with one person being taken away by ambulance, I accept Princess can't control Chinese Immigration but they can control the comfort of their guests whilst waiting in the queue, there was 2 air-conditioned terminals in use, the first one was used to drop off your bags, you were then ushered outside into the heat to queue for 1.5 to 3 hours to get to the next terminal, they could have seated us in the first one and shuttled us over when space was available, reading other reviews about the Majestic from Shanghai it seems they encounter this issue often and have failed to resolve it.
The ship itself was impressive to start but as the cruise went on you encountered the flaws, the Hollywood area was our favourite area, we found most of the bars to be too small only seating round 20 people and very hard to get a seat most of the cruise, The Theatre and Princess live rooms were cramped with tight seats and nowhere to put your drink, overall it did not live up to their marketing videos.
