My inlaws had to cancel right before their cruise because my FIL had a heart attack and had to have open heart surgery, so it's a good thing they had insurance. I don't think twice about purchasing it for a cruise, especially since I have a DS that has been to several different emergency rooms while on vacation. We completely stopped traveling for a few years because he always got sick. Our cruise this year was the best ever, and hopefully we can make it two years in a row without an emergency room visit when we cruise again next May. We even got our insurance within 7 days of booking our cruise just so it would cover any pre-existing conditions. My DH has major back problems and I could just envision him not being able to move when cruise time rolls around again. I'm not one to take chances.
