Here is a quick article from the Wall Street Journal giving advice on buying Travel Insurance
"Purchasing travel insurance is a bet on disaster. But there are times when it's a gamble worth taking—whether you're hedging against cancellation, injuries, thefts or other calamities.
Travel experts say insurance makes the most sense for extended trips out of the country, cruises and stays at vacation-rental properties. But any trip can be upended by illness or other circumstances, including missed flights, weather, natural disasters or political unrest.
Since the summer of 2010, one in eight U.S. adults have had a trip aborted or cut short or they have changed travel plans and lost deposits or nonrefundable tickets. Of those hit, only 29% had travel insurance, according to the U.S. Travel Insurance Association. "The bottom line is it's about the money," says Ed Perkins of SmarterTravel.com.
Travel-insurance policies can be confusing and loaded with limitations and exclusions. Plans cost, on average, 4% to 8% of the total trip costs. Prices vary depending on the length of the trip, the age of the travelers and the options. Roughly speaking, a $5,000 trip will put you back $200 to $400.
You may not need travel insurance if you're already covered under a life, health auto or even a homeowners policy. So check those first for benefits you might already have. Remember: Medicare doesn't cover you outside the country.
