if you can get it, i suggest getting medivac as well..
sounds like overkill, but we never go anywhere in the world without it, including to the US..
medivac covers a medical plane to take you back home...
in other words, if you're in such serious condition that the only way to get you home is by medical plane (a special plane with a doctor and nurse), the insurance covers it..
without the insurance, the cost would be over $100,000.....
if you're that ill, you really do want to be back home..
i have a cousin who had a stroke while on business in china....thank god for the medivac insurance that got him back home...
i don't know if you can get medivac insurance in the UK, but if you can, i would... it adds to the cost of the insurance, but for us, the peace of mind is worth it...
