Hi there,
I have just started travelling abroad, and I agree that Staysure were the cheapest company to go with, and although I have not made a claim, they seem a very good company to deal with.
My wife has heart issues and I have Myeloma in remission, but we were able to get cruise cover for the Med (including helicopter evacuation from the ship if necessary) for both of us for about £140 for a week.
Hope this helps.
Regards, Tony
