Ok so following info in Sparky74 post, I just checked Franks travel insurance PDS and it doesnt include the snow sports option which seems to be even just going on ice/snow??? I did a dummy run and it looks like its $400 to add that option in........ arrggg which doesnt auger well if they cancel the excursion as in Marks case!!!!! I will phone the office on Monday and check if landing on a glacier counts as snow sports. Then will reassess if the said excursion is worth it.
