One of the most expensive parts of traveling is the hotel. But, what if you could stay in a full-sized home for no money at all? Thousands of people do it every year. It's called house-swapping and it's a great way to protect your pocketbook. What makes this couple unique isn't that they're well traveled. It's that despite living abroad for months at a time, they've never paid a dime for a hotel. That's because they're into house-swapping. They simply exchange their Florida home for one in the location they want to visit. Sometimes for days, sometimes for months. "Most of the time, your lodging is your biggest expense in any trip. When you don't have that, you're spending the same money you would at home." Basically the process is like internet dating. You put pictures of your house in special magazines or online, you say where you're interested in going, then sit back and see who wants to swap. And as far as having strangers staying in your house? This couple has done it 20 times and never had a problem. They simply do what internet daters do: they get enough information to feel comfortable before they agree. Their advice on the whole experience? "We would strongly recommend it to a family or a young couple that finds financial difficulty in any kind of expensive travel."
