In reply to BruceM:
Thanks folks. Don't mind hijacks - all good Arolla talk.
It may be the same with loads of snow this year too given conditions in other parts of the Alps.
Whereupon, perhaps the question should be: does a lot of snow rule out too many of the fun things in the area like the Tsa?
At least in Chamonix and elsewhere there is lower rock to do if conditons up high aren't best. Arolla doesn't really have much of that from what I can see.
