I use a company called CSA Travel Protection. They're one of the providers on the site IBCRUZIN' posted. I'm an agent and have a professional relationship with them so I may be biased. As a result I know more about their policies than I do of any others. I know from the posts here there are a number of good providers out there. I have had clients with claims and have been very satisfied with how they've handled my clients, without exception.
