I'd suggest trying Bembridge on the Isle of Wight (just off the South coast of England, right in the middle).

Good tarmac runway, right on the coast, next to a very pretty beach and village, on-site customs, fuel, places to stay (in case the weather turns), and a superb lunch - particularly if you eat in the "Crab and Lobster" (
