P&O not for teens

P&O cruises have the worse age restrictions, I’m 17 I am not allowed in the spa, certain restaurants, certain lounges, fitness room or to leave the ship on my own. I get the not serving alcohol to people under the age of 18 but really still classed as a child even on a child’s card at 17. They have trivial busy work and activity’s for teens that are designed to keep them out of their parents hair. They need to be more Flexible because it is bad for teens and not fun when their entire family is doing an activity and they are not allowed because of their age. Understandable to young children 16 and under but teens just want to chill with out the 3 to 15 year olds but yet we are put amongst them because we cannot go to a lounge we’re people are not screaming and carrying on while the over 18’s are able to sit there and they are often the most immature
