You just bought a fantastic, but nonrefundable, vacation. Should you buy trip cancellation insurance? If the money you stand to lose is more than you can afford, then yes, but getting paid is not as easy as you think. Medical emergencies are covered only with documented proof. Being called for jury service or military duty is often covered but business emergencies are not. Some cruises and tours only refund a sliding percentage depending on when you cancel. If you don't follow the refund rules and procedures exactly, you could also lose your reimbursement. Insurance companies often do anything to keep from paying claims, so don;t make their job easy. Read the fine print -- twice.
