Q: I'm driving to the Poconos for Thanksgiving and flying to Paris for Christmas. Should I buy travel insurance for both trips?

A: You should consider purchasing travel insurance if you can't afford to lose the money you invested in the vacation or if you can't cover unexpected medical and emergency costs at your destination.

Most comprehensive travel insurance policies offer three types of coverage — financial reimbursement for trip cancellation or lost baggage, medical coverage and emergency medical transportation. You can also buy a la carte coverage from some insurers.

The cost of the policies depends on the type of coverage, your destination, your age and gender and the cost of your trip.

For example, an all-inclusive package for a $3,000 trip to Paris for Christmas week runs between $278 and $550 for a 60-year-old and between $172 and $367 for a 30-year-old, according to InsureMyTrip.com.

While you probably can go without coverage on your road trip, you might want to think about insuring your more expensive vacation that has nonrefundable deposits.

A number of unforeseen circumstances can cancel or interrupt your vacation: bad weather, an unexpected illness, a sudden death in the family, even jury duty or a job change. Travel insurance with a reimbursement provision keeps you from swallowing the costs for airline tickets, vacation tours and hotel reservations.

''Any time you would incur a loss from nonrefundable purchases, you should have travel insurance'' said Lila Ford, owner of travel agency Gallery of Travel in Rochester, N.Y. ''If you're paying $5,000 or $6,000 per person, what is $600 more?''

Additionally, travel insurance reimburses lost baggage during a missed flight connection or other situation. However, Ford said to check with your credit card companies and homeowner's insurance to see if they also cover lost belongings.
