A family should not rule themselves out if they do not have an extra bed as one can usually be arranged. Our home is not large enough. The size of the host family home is unimportant to the student. Many students come from very modest homes. We no longer have children in our home.
Many students delight in being an only child for a few weeks.
One of the special aspects of a cultural exchange program is it works well with families of all types. Busy families make the best families. The students are busy themselves Monday through Friday so the usual routine should not be greatly disturbed. The students like to see much of what is going on in this new culture and the busier the family is the more the student gets to see. If there is a problem that can not be solved we will of course immediately move the student into another home.
