Europe Travel Medical Insurance
Best family travel and medical insurance for a year long trip?

My family and I are going on a year long trip across the US, NZ, Australia, Singapore and Europe before coming back home to the UK. Does anyone know the best insurance option? Separate policies for each country or one policy to cover 12 months? Most family policies are ‘multitrip’ and these are not suitable as we are travelling continuously (and independently). My kids are 6,7 and 3, so obviously we need great medical insurance. Please help!
