This was a number of years ago, but we had to use the trip cancelation insurance because I had to have belly surgery in the coming month, and it worked fine. I had to send them a copy of a letter from my doctor stating I had to have the surgery, and I was able to get refunded with no question. We moved the trip to a later date, and everything worked out fine. I would advise to call Reservations and find out what the current procedure is in terms of documents, it might be different now. If I had to, yes I would use it again.
