Thanks for the suggestions all, (specially A & C who has obviously read my question re: Draycot in another thread
). Some interesting ideas there, haven't been abroad yet but definitely on the list although will probably go with a more experienced pilot first time around. Texel sounds like an interesting alternative to Le Touquet which is usually greeted by rolling eyes when mentioned (father in law likes that one though!).
Isle of Man. Great idea, always wanted to go there and has the added bonus that I can then really impress by indulging in my steam railway fascination!
Got a good list of places to check out now, further suggestions welcome though!
