Surprisingly the disembarkation on Arvia on 28th April was shambolic. Late arrival didn't help due to medical emergency and strong head winds across BoB. One thing clearly stated on letter sent to your cabin is that you are expected to vacate cabin by 8am. Your dedicated departure lounge time is given but you cannot go there until 10 minutes prior to stated time. So where do you go for what could be 90+ minutes. People were wandering around aimlessly, sitting on floors in corridors and on stairs so blocking stairway. Spoke to officer at my departure lounge and was not interested at all. When asked where we were supposed to go she said it was not her problem and just shrugged her shoulders with a don't care attitude. I have written to P&O a out this issue which is an H&S issue but had auto reply saying received but not yet had a response.
