Thanks for your suggestions, Giok and MudGuard. I'll try them out as soon as I've found a learned article in the Lancet about either. I might also try an attack of my (by now chronic) anglophilia ...
Actually, I'd just need a day or two to get there. What really puts me off is still the fare (I'd like to take my car for sleeping) and the exchange rate. It costs us Continentals a fortune to go to Britain these days, let alone eat (and drink) there!
Maybe I ought to overcome my fear of flying and check out Luebeck to Stansted - without the car, of course.
