We love to travel with P&O one of the reasons being it gives us a chance to dress up for the formal evenings which, lets face it is not something we get to do that often. The ships have a wonderful atmostphere on these evenings, we too have seen jeans and anything else some people see fit to wear, my guess is that they dress for dinner and then change their clothes in order to go to the bars. We have cruised for a number of years and have really noticed the decline in dress standards.
