hosting foreign exchange student?

well i have an oppertunity to host one for 20 days this summer

and i was wondering if any of u have ever done this, and how it worked out.

like i have soccer prac like 3 times a week and like 2 games a week in the summer. most of my games are like

2-2.5 hours away (traveling team)

so i was wondering how it all wud work out. also they need their own bed, is a futon in our basement family room enough? i think it is ok. is like a split enrty home, so its not really an underground basement. its all finished off and stuff. we spend a good chunk of time down there.

so any tips, stories, or ideas welcome.

oh and i have an older brother (hes 18 im 16 in the summer)

and my parents have the summers off.

thanks!
