Wasn't really sure which category to put this under ... Anyway, just thought I'd share a "find" with you all. Travel insurance, really affordable prices, and they insure ANY age REGARDLESS of pre-existing conditions!! I'm not sure about world-wide coverage, as I only needed to enquire regarding my parents who were visiting us here in France. I got the pair of them covered, both in their 80s and my dad has serious heart problems along with a few other health issues - for a grand total of €120 - that's around £84, for a 3-week stay. To put this into perspective, last year the only people I could find who would insure them was Saga - and they charged nearly £600 for 2-weeks-worth of the same cover!!!!!! Who are they? ExclusiveHealthcare.com. Might be worth a try, especially for those of you who only ever holiday in France.
