I don't understand people who book on P&O knowing about the formal nights then complain about them. If you don't want to do formal you don't have to, we missed one night out of four and regretted it. If a restaurant on land stipulated you had to wear a tie would you go without one?🤔
There are complaints about formal nights and that P&O don't have amusements on the ships. People know this when they book, so why complain about it later. Every cruise line has different amenities, go with the one nearest to what you want and accept that there could be some things you don't want. 😀
No company will keep 3,000-5,000 people happy but they must be getting most things right as they still sail every week.
