I have to disagree very strongly with the overall sweeping statements about the area being overwhelmed and too busy with long lift queues.
We have had a chalet in Samoens since 2005 and ski here all season from December to April.
Apart from New Year week and some school holiday periods in February, the resort is pretty much deserted. It can be busier some weekends as day trippers come to ski but midweek it's very quiet.
Just be aware of the busy periods and book accordingly. All resorts are busy at New Year and half-term. Christmas week, much less so.
There are new lifts put in every year.
If you require transfers from Geneva, please look up Go Massif Transfers to Flaine, Morillon, Les Gets, Samoens etc. Very frequent and inexpensive. We have used them for 8 years and highly impressed by the standard of service. Rates vary from shared to private transfer.
You can even book your lift passes online with Grand Massif to prevent queuing at the lift. The season pass is an absolute bargain at around 439 Euro from Decenber to April. That's a 50% discount! 254 Euro for up to 17 yrs.
We love this area and after skiing all over the Alps for 40 years, wouldn't be any place else. Samoens is beautiful both winter and especially in summer having been awarded special French heritage status.
Certainly one of the better kept secrets rather than the average soulless purpose built resorts.
