Some destination countries require travel insurance, however some do not. Many travel insurance companies offer travel protection plans to help protect you and your travel investment against the unexpected. Each participant should make an informed decision about whether or not to purchase travel insurance, and if so which provider to use.
Travel insurance can cover a wide variety of circumstances ranging from cancelled trips to overseas medical emergencies. It's important that you read the fine print of any plan you choose so that you understand the exact conditions under which your expenses will be reimbursed.
Check with your current health insurance provider as most US based insurance companies do not extend coverage to foreign countries. Therefore you may want to look into supplemental coverage options for your travel dates. Please note, some benefits are time sensitive and must be purchased within 10 days of making trip deposit. There are many reputable companies you can shop based on your individual concerns. Each will have different package offerings for your side by side comparison and review.
