Not brilliant weather when we went; poor visibility and rain lower down (lots of snow as well though), but I think this resort and the linked resorts compare well with any of the other big areas.
Good central town with lots of usual facilities, good restaurants and bars/shops etc, Good ski bus and plenty of free parking near the main lift.
The skiing in Les Carroz is good and mostly tree lined, most of the more challenging stuff is at Flaine. Takes about 20 minutes to get over there if a reasonable skier.
The lift system has seen some investment but could do with a bit more in places.
A good resort for beginners and intermediates, but not so much in the way of challenging runs.
We booked here partly because they advertised a new leisure center with sauna/swimming etc. Unfortunately, this did not open (some dispute with the contractors). That was a bit disappointing but it should open next year (2014).
