Unfortunately Friar my list is rather longer than your's but I'll certainly give the company a try.
Edit.
Well I tried O2 this morning. The annual insurance looked really good at £203 - considering I had to declare 10 conditions (or 12 if you include associated conditions). Then I read the small print that told me multi-trip policies cover trips of less than 31 days. So I tried a quote for the 60 days my single trip would last - result £592 (almost the same as Saga, and they would have covered Hilary as well).
Why so much difference in going on one 60 day trip rather than many 30 day trips? Incidentall, without medical conditions the annual rate is £34 and the single trip £122.
