If you travel somewhere that has medical care that is not up to your standards, you will likely want to get someplace that does meet your standards. Here is an example, you are on a cruise ship and you have a neurological emergency. You are put off in a port that does not have a neurosurgeon. If you have medical evacuation insurance, you may be able to get the help you need. If you don't, and you don't have a $50,000 credit line, you may not get the help you need. It is pretty simple.
