I'll go first. We went to Les Gets with Ski Famille. Loved the resort - nice town, just over an hour from Geneva, lots of places to eat, shops to browse, decent local ski area ideal for confident intermediates, 360 ski school for DS1 (age 4) was good, lots of wide-open runs to progress to for a beginner, weather was lovely, chalet was walkable to all amenities, snow was good, chalet food was excellent.
Only downsides for us were: we didn't have much in common with the other chalet guests, the playroom was tiny, no car seats on coach transfers, one of the nannies wasn't very good (but the other two were lovely), some of the lifts are old and slow (we went at a quiet time of year it wasn't a problem - in Feb I'm guessing it's an issue), and none of us slept very well because we're used to having more space and doors/corridors between us at night.
Overall, it was a great holiday and DH and I loved being able to go out skiing child and guilt-free! Not sure what we'll do next year, but would definitely consider Les Gets again.
