When looking for travel insurance, there is a dizzying array of companies, policies, plans, restrictions, and conditions. What should a short-term traveler look for in an insurance plan? What things should you watch out for? Are there any companies or plans in particular that are commonly recommended for travelers?
Edit: To make this more specific, I'm looking for a general travel insurance policy for a single traveler in good health traveling for a few weeks to a few months. It should be comprehensive enough to cover basically any medical issue that could arise while traveling in most parts of the world. I know there are hundreds of plans that fit this criteria, so my question is: are there any major aspects that set some plans apart from others, or are they basically all the same? Are there a few companies that are frequently highly recommended for travelers, or is there not much difference between the companies out there?
