I buy
travel insurance, but it has NOTHING to do with losing any of our travel fees. It has EVERYTHING to do with health insurance coverage.
We have good health insurance, but when you travel out of your area, and you have an emergency, your insurance coverage will be very different from home. You might have to pay up front (or be billed) and then seek reimbursement from your insurer.
If you have coverage where you have to pay a substantial percentage for "out of network" care, that can add up very very quickly. Your policy may make exceptions for "emergencies," but the emergency is over pretty quickly, and if you need a few days of in-patient hospitalization afterwards, your insurance company will probably tell you that you should come home and if you stay in the hospital in Florida you'll need to pay out-of-network rates because it's not an emergency that you stay down there.
A few days in a hospital could easily cost you $30,000. If you're responsible for paying 40% of out of network costs, that'll be $12,000, please.
You may have needs not covered by your health insurance at all, such as an emergency medical flight, or the opposite, the need for a rental vehicle to drive home because you need oxygen and you can't bring that on an airplane.
My wife is a physician, and every few months she hears FINANCIAL horror stories from people who got hurt while on vacation and had to spend thousands out of pocket or are in the process of having their credit ruined by out-of-network medical bills that they can't pay for themselves.
No way I'd bother paying $134 to protect myself from losing $200. We buy it to protect from the tiny chance of ungodly medical bills that our normal health insurance won't be so helpful with.
