It’s a lovely place, remote, at times bleak and as others have said not a huge amount to do there, but a lighthouse tour, Derek Jarmans cottage and the power station offer a couple of days worth of entertainment, or one full day.
But venture a bit further and you can visit Rye, Hastings, Camber and Tenterden. Or head the other way Folkestone, Dover, Deal and Sandwich. Of course you have Canterbury too although I think it has gone downhill in recent years it still has lots of tourist attractions. Don’t forget Wye, Chilham and Winchelsea. And don’t forget Bodiam.
Plenty of castles about thinking about it.
Lots of water sport available along that stretch of coast too, golf too if you like although a bit hard to get on some of the courses.
All of those are pretty much within an hours travel, as are the north downs for some excellent walking.
