La Plagne in general is a very nice area. Lots of little villages, so no huge ski resort vibe, rather a nice village atmosphere unique to each area. There are lots of local French people working in the villages rather than foreigners doing ski seasons, so there is a good vibe.
Crete Cote is very small but close to 1800 and there are good transport links between villages to go out in the evenings. There are lots of very nice bars/restaurants on the pistes as well.
The ski domain is huge and an all-rounder. Great skiing for families, particularly children, with lots of easy slopes, but there is certainly lots to do for more advanced skiiers.
I highly recommend the area.
