We stayed at the Crans Ambassador over a long weekend and particularly liked the fact that the hotel is very child friendly. Our daughter was given a welcome gift upon arrival, her own child-sized robe and slippers and really enjoyed her time at the swimming pool after skiing. The pool is always available to children (I think some other areas of the spa are reserved for adults during certain hours) and they have foam floats and noodles.
The staff were courteous and genuinely eager to help. Weeks before we arrived, the concierge provided me via email all the information needed regarding ski lessons, ski hire, transportation etc. They actually arranged our lessons and we got all the equipment from the sports shop adjacent to the hotel.
We stayed in a deluxe room on the 7th floor (same floor as the reception), it was lovely and reasonably spacious with its own little terrace with mountain views. There was a good variety at breakfast, my daughter particularly liked the crepes and pancakes. The closest ski lift is 5' walk and it takes you to the nursery slopes where a lot of the ski schools have a meeting point. We had arranged for the ski instructor to meet us outside the hotel the first day.
You can get ski passes at the hotel (but only for a full day). You can get half day passes from the tills near the ski lift.
The hotel is closest to Montana, about a 10' walk but the hotel shuttle is usually available to take you / pick you up (we didn't have a car).
