If you are going overseas you need travel insurance. Rule number 1: never buy travel insurance from the company that is providing your trip. If they go bankrupt and you are trapped in an airport who would help you? Instead look for a third party insurance company offering the best deal for you. What are you concerned about? Getting sick overseas? Your travel company going broke? Terrorism or lost luggage? Are you renting a car or going scuba diving and worried about getting the bends? Buy a policy that covers your concerns. It is hard to do all the legwork yourself, so use a comparison site like InsureMyTrip.com. It allows you to compare companies and coverage and get the best insurance for the lowest price.
