I just got off the panorama. Boarding the ship was a zoo and I’m platinum. My boarding time was 12. Yes there was a designated sign for priority boarding, however once you went through, there was not another designated area for platinum guest. Maybe if I had an earlier arrival perhaps. It took an hour to board and once you board, you are required to go check into your muster station and you cannot go to room until 1:30.
Leaving the ship was much easier. The ship did arrive at 9:30 and the cruise director announced it was going to take at least 45 minutes. If you elected to take your luggage off, they would call you by your muster station. ( I chose to put my luggage off the night before). Fortunately the priority guest met in the liquid lounge, and we were able to leave about 10:30. Met our transportation at 11 after retrieving our luggage, and going through customs. (Get a porter as they have a shorter line for customs with a passport)
