Don't forget that your personal insurance follows you to the rental car. Most of it is just upselling IMHO
I have heard (and don't know if it's true or not) that with "double coverage" neither party will pay. Each one say it's the other's responsibility and leave the renter holding the bag. Like I said, no idea if it's true or not but I can see where that could happen.
Close. we had this once with medical insurance in he US of A. Son had to be rushed to hospital and, we had insurance through VISA and through work - it got paid but not without a lot of squabbling between the two companies - which didn't affect us at all except it meant we started getting "please pay now letters."
J-P - how would that have been different if your son had become ill while traveling in Canada?
I have never heard of a company suing - though I suppose they could.
