Hi - we are from Canada & are experienced cruisers however we have never cruised P & O. After our cruise ends (expected arrival 0600 hrs) we need to catch the train back to London as early as possible that morning. Can anyone share their experience regarding the earliest we can disembark if we do self walk off with our luggage? Also how long does it usually take to get through customs at Southampton? We would like to book train tickets and not sure if 8:30 am train departure would be too early. Any advice would be appreciated.
