For families with kids, this is a great deal. Sometimes, a home exchange comes with the use of the family car, so you also save on the cost of transportation. Kids get a chance to meet other kids, share cultures and experience the daily life of families in other countries. And of course, it's inexpensive. You may have a nominal charge, but it's always a good idea to give a gift of appreciation, however.
Kids can exchange gifts, too.
Another terrific educational alternative lodging for families is a farmstay. In many countries, including the U.S., family farms and cooperative farms offer accommodations and meals, as well as an opportunity to take part in farm life. Feeding animals, helping with the harvest, planting and even churning butter are all activities that kids will enjoy. Farmstays are also inexpensive, compared to hotels, and offer families a chance to get outside urban areas. Many campgrounds offer cabins, as well as tent sites, so you needn't sleep on the ground.
