Adventure Weekend in Boston? (UK)?

East European immigration has given me a money-making idea. I would run 'Great Escape' theme weekends. Players would be told 'You have escaped from a POW camp and made your way to a Baltic port, where you hope to get a boat to neutral Sweden. The population is either hostile or scared of the political police. Hardly anyone speaks English. Your mission is to find a friendly contact and escape capture for 24 hours.' Then I'd dress them in old civilian clothes and drop them outside Lidl in Boston, Lincolnshire. What do you think?
