We had a near disaster when our reservation was not found by our chamber d'hotes. But our hostess made it work. I think she may have given us rooms of her kids who aren't living there any more full time.
Unfortunately, the weather betrayed us when we started up the mountains. But we did really well and arrived before noon at our albergue, Orisson. It is 1/2 the elevation to the top and 1/3 the distance. We are watching the fog from our window in the dormitory, getting ready for dinner at 6:30, thinking the place Is a lot like a ski lodge with too much wet gear on the floor, not enough chairs, and abundant joyful noise.
