So here's my story...
The very first time I ever purchased trip cancellation insurance was for a trip to Europe with my husband and his parents. We spent over 1 1/2 years planning this 3 week 'extravaganza' (we had traveled there several times previously). Pinging off the walls with anticipation. Fast-forward to 1 week before the trip -- my husband's sister's ex-husband, who hadn't exactly accepted the realities of the divorce, started staying up all night writing pot- and alcohol-fueled emails to his ex-wife. He very carefully avoided directly threatening her, but alluded to recent news stories concerning ex-husbands who had killed their ex-wives. Charming. And very scary. Four days before our trip, my father-in-law (God bless him) decided he just simply couldn't leave his daughter. What if something happened and he wasn't here? (We all knew the slim chances of that, but sometimes fear wins out.) So, my in-laws cancelled 4 days before our trip. My husband and I, after much deliberation, decided to go on; he'd moved heaven and earth to get 3 weeks off. The point is, all 4 of us could've cancelled and been out $0. As it was, my in-laws had no difficulties in cancelling (albeit due to his dangerously high blood pressure - and he's a heart patient), and we could have cancelled, too. Now, the fact that he'd had a quad bypass and an especially bad family history of heart disease makes this case a little out of the ordinary, but the point is you just can't predict the crazy ex-husbands of the world. Perhaps YOUR ex-husband is a bad case of pneumonia (are there good ones?), a recent cancer diagnoses of a loved one, the death of a dear friend, whatever. READ YOUR POLICIES VERY CAREFULLY!
Shop around carefully. I'll never travel without trip cancellation and evacuation again. Baggage ins - nah. It's on my back!
Mr. Ex-Husband was not even on our radar 2 weeks before the trip...You just never know.
