Tunisia - the locals can literally not see a woman without popping their heads out of their cars, or worse a bunch of men from the buses!
Barcelona - overrated, just a normal city.
Panama - the difference between the poor and rich is extreme! Any good beaches are far away from the airport.
Durdle door (for now) - I went a few times prior to having kids, but I cannot imagine going now at all! No toilet or rubbish bins once you walk down the VERY steep steps and onto the beach, and do not want to imagine having to walk them back up! I was tired enough when I was fit, slim and single, don't want to imagine while I'm now the opposite plus having to carry my children's belonging too!
