Answer
Ring the airlines, perhaps you wont be able to get a budget airline, but the traditional airlines are sometimes as cheap. particually if you dont mind where you go to.here is a nice option - get the train to south shields, ferry to amsterdam, overnight there thenferry home again. plenty of time for stag do mischief!
