We had to use travel medical on our March break trip. It was an option with my work benefits, and for $15 for the family for the year, I said what the heck...We typically do purchase it, though I can't tell you who now. Anyway, I thought the work stuff would do us, and boy did it ever. Dh ended up hospitalized overnight, and our return trip had to be rebooked. The hospital stay along was $14,000! That works out to more than $500/hr!! Then the airfare was a couple thousand more (last minute booking--I could have flown us RT 3 times for the amount it cost!), hotel I didn't get to research, etc. The insurance was through Sunlife, and it was great. It was a bit of a hassle to file the paperwork for our own expenses, but they were really good to work with, and kept me from freaking out at the time by being reassuring and helpful. (Note it was even a pre-existing condition, that was stable, and we didn't get one minute of grief.)
Not sure if that helps as my option--through work--doesn't seem to be a choice for you at this point. But with a dh suddenly in the hospital 12 hrs before we (2 kids and a dog) were to fly home, I was so, so grateful for it.
For the record, we ended up at Celebration Hospital because it was closest. It was a lovely facility, but they seemed VERY cautious, and my local friend told me later she wouldn't have sent us there if she'd known.
