Living Abroad?
Home swapping is great for ex-pats coming 'home' for a holiday. You can have free accommodation without imposing on friends and family for weeks at a time. If you swap cars as well, you can use your exchang home as a base and travel round catching up with others.
With your own 'home away from home', you can live like a local and enjoy the day to day things from your old 'home' - without feeling like a tourist.
