Travel insurance is a really good idea to buy if you are going on an extensive trip during a time of year when weather can be an issue. I can't count the number of people I know who have planned trips during a time of year when the weather can be unsettled, and they either got stuck at airports or had catastrophic storms to deal with. Travel insurance will allow you to cancel your trip and get full refunds on air fare, hotels, and other types of service that they paid for up front.

Most travel insurance has an option for car insurance for rented cars, and anyone who knows how expensive the policies that the car rental companies charge for daily rental would want to include liability and collision coverage as part of the travel insurance package that they purchase. Travel insurance can be used for tours, flights, cruises, and other types of travel, and is well worth investigating if you are traveling during the winter months, or going to a hurricane-prone part of the world during the late summer.
