Sorry a bit cheeky to put on AIBU - but - it's an important question!!
Brighton - great vibes, creativity, open mindedness good schools - but overpriced and the countryside isn't amazing and there are no gardens.
So what is the alternative! Where else is open minded and fun and has sea air and countryside but is not ruined by hen dos and property prices. And needs to have good schools.
Sadly, I have to write off the whole of Kent as I don't approve of grammar system. Unless there is somewhere in Kent with good secondary moderns.
