Skied a 4 day break in Flaine/G Massif in 08. The architecture is really quite engaging, not ugly. It's made for looking out of, rather then looking at. Different, perhaps, but sharp and rather cool. Link (singular and, crucially, weather permitting) to the rest of the ski area provides softer and easier (early intermediate) skiing down to Samoens, Les Carroz and Morillon. Prices, at the time, were rather stiff for beers, food etc. considering that this is, primarily, a self catering resort. I recall a pint costing 7 Euros par at the time and a meal on the hill around 12. Apres was fairly quiet. The Flying Dutchman, esp on bbq night, and the Perdrix being the pick.
I intend to revisit the Grand Massif in March 2015. I like the size of the area, short transfer, variety of the ski villages, affordability of accommodation and lack of pretension that comes with this proper resort. I just hope the beer prices have not gone up!
