In reply to Simonfarfaraway:
The big issue is to make sure you have medical coverage - even something annoying but trivial, such as a fracture, will set you back many thousands of £. On Supertopo some time ago there was thread about the cost of being bitten by a snake if you are uninsured. Figures around $100,000 seem to be the ballpark....

so £115 for a week seems reasonable. I pay considerably more than this for medical insurance. But I'm old.
