This is one of the top priorities while travelling and having this in order is I believe vital for a none stressful vacation. This applies to any destination in the world im very sure of.

I have always had varying degrees of health insurance in addition to the coverage that my ongoing domestic health insurance offered me. Honestly though I am not sure it is something that would cause me stress if I didn't have it.

Do you really need additional travel insurance? I've never thought of that. I have full coverage already. I have no idea if I'm covered in another country.
