Not being disrespectful at all. I have done 74 cruises with 5 different lines but most with P&O. As I have said before, I travel alone and have had fixed (late) dining on all cruises, except Iona of course. I use the MDR for all meals, never the self service buffet. I do not want to dine alone, so obviously do not use the speciality venues either. Try to understand that successful, sociable cruising solo is far more enjoyable on the smaller ships which you, as a couple and younger, would probably dislike.
