Everyone is looking for a good investment these days. And with stocks, currencies and companies all crashing, some are finding that taking the trip of a lifetime is actually a smart move right now. Prices are good, crowds are fewer and the dividends like expanded worldview, lifelong memories, the satisfaction of boosting the global economy -- can't be easily snatched away.

Later this year, they are planning a trip to Patagonia. "We're using our capital now," says Sylvia, "And why not? We're not getting any interest in the bank. If it's a place we really want to go, then we will go. We may as well travel while we're fit and healthy. "
