I also have travelgaurd for my trip. not expensive at all, and covers quite a lot.
Something else you may want to consider is a medical passport, especially if you have medical conditions. I am having my cardiologist make one up for me for my trip. I have a congenital heart defect, and one of the support associations here came up with the medical passport, that allows the dr to fill in our specific defects, if we are on coumadin or another blood thinner, if blood pressure is best out of one arm, what our "normals" are--- since our "normal" can sound VERY bad to someone who is unfamilar with us. example: my mom also has a CHD- one of the most complex,CC-TGA, her arteries, and vessels are backwards.. right is on the left, left on the right side, ect. When she firts met her new regular GP-- he said: had you not explained your defect to me-- i would be calling an ambulance right now, because nothing sounds like it should, because it is all coming from the wrong places!
I would strongly recommend something like this if you have a major medical condition. I will have my medical passport, stored along with my regular one-- and I also have my medicalert bracelet.
