Having faced this issue a few years ago we found plenty to amuse the wives whilst we went off hooning it.
The Panaromic from the top of chatel down is a very easy green, the DH boys tend to stay off it also.
+ 1 for round the lake Montriond nice day good opportunity to do some swimming as well.
Golf in Avoriaz (maybe your thing)
loads and loads of walking, the hike from Morzine to Les Gets then bus back.
Chamonix is 40 mins by car and is very pretty
Horse riding centre just outside Morzine (again if thats your thing)
There was a zip line thing on the top of Chatel not sure if thats still there though.
Some stunning towns and villages along Lac Leman (SE corner) particularly Chillon Castle which is just outside Montreaux.
