My half sister is 18 and is bringing two girlfriends and staying with me for 10 days in November. They are celebrating the end of their exams. I don't live in a particularly exciting city in Germany and I have a 7.5mo DS. None of the girls have any German language. My sister says not to worry about planning trips etc, but I think it will be a must. Any ideas of how I can keep them occupied will be gratefully received.
Plus: I am also worried they will be expecting me to cook and clean for them, but don't want to seem like a stodgey old bag for sitting them down the moment they arrive and explaining that I will not be 'mothering' them during their stay.
