How much money are you giving them for this? I don’t think the war will be a big deal in Italy except for increased costs. But what about London or Paris where they could take metro around and then do some day trips via train or tour bus. I wouldn’t send them to Greece or anyplace that’s a known party spot. With shows and museums and shopping in places like London and Paris they can probably keep themselves busy without the party scene. But where do they want to go?
