Free time activities

Are we talking with or without film crew?

If they're from Russia, organize a tour of the local tractor factory.

Just kidding. Try to line up something with a local flavor. In my area, I might get them involved in some of the ancient Indian pueblos. You should form a sense of whether the activities should be mostly fun, or mostly educational.

Ask them what type of things they are interested in. Then, look for some activities related to that.

If you give us a bit more specific information, we might be able to narrow down the suggestions a bit for you. What country are they visiting? What country are they from? What age are they? What are they studying?
