After hours of searching and blog reading you can safely save all of this time and head for only one option:
We found that Nomad had an excellent policy that allowed for travel back to a home country should an emergency arise. They not only allowed for travel back to your home country but also back to another country if the need arose and as I have a Mum back in the UK and Kristi a Mom back in the USA then this is a great security blanket should we need to rush back to one of three countries. Their standard policy is very competitive and upgradable for extreme sports along the way if that is your thing.
