Some would say Bill Nugent has the worst luck when it comes to planning a vacation. Bill Nugent, "Once we had a death in the family. I had to cancel a trip three days before, and the second time, I injured my leg and had to cancel it, maybe two to three weeks before." Fortunately, Bill had bought travel insurance for both trips. He got back most of the nearly 12-thousand dollars he had laid out. "Travel insurance is a two billion dollar a year industry, covering everything from natural disasters to personal medical emergencies." But do you need travel Insurance? Consumer Reports Money Adviser says - maybe, but buy wisely. For instance, don't buy insurance that covers small losses, like lost luggage. And if you're worried about dying in a plane crash, skip flight insurance. Instead, think about term life insurance. It covers you no matter what the cause of death. Greg Daugherty "Before you buy travel insurance, first check the insurance you already have. Medical emergencies may be covered by your health insurance, a fender bender by your credit card." If you're traveling overseas, which can require additional health insurance -- consider medical travel insurance. Greg Daugherty "And if you do decide you want travel insurance, it's better not to buy it from a travel agent who may be more swayed by high commissions than what the best policy is for you." Instead, go to an online broker like Insure-my-trip-dot-com, which sells coverage from 21 different carriers, including CSA Travel Protection, Med-Jet Assist, and Travelex. As Bill Nugent learned firsthand, a little insurance could go a long way --when things don't go according to plan. .."
