One way to hedge against such complications is travel insurance. After years of fielding letters from travelers whose plans were derailed by illness and accidents, I highly recommend buying travel insurance any time you’ve got more money paid for a trip than you want to give up. Sites such as Squaremouth.com, InsureMyTrip.com and Quotewright.com sells package policies that will reimburse you and your companions if you have to cancel or alter a trip due to illness. To cover pre-existing conditions, most policies must be purchased within 7 days of your initial trip payment.
