Money saving, you have only your transportation to pay for.
Free home, RV, caravan…, whatever the case may be and a free car if you concluded a car exchange deal as well.
Free activities at times, for example, if your exchange partner has skiing equipment, golf club or bikes.
You get to learn the culture of the country you are visiting.
Friendship between the exchange partners.
Your home and/or vehicle are watched while you are away.
You can even go far away from home and visit other places.
You will have general information on tourism, the cost of living etc, thanks to your exchange partners.
There will be someone to welcome you and drive you back to the airport.
The comfort of arriving in a fully furnished home and having all that you will need (bedding, TV-video, washer and dryer, computer in most cases…)
You can always arrange with your exchange partners, for example if you have a baby and you need a crib or a safety gate. They can get it from a friend or an acquaintance. In exchange you can lend them your sports equipment. What a great deal!
