I also skied 3 vallees but stayed in Val Thorens. It was awesome.. we ended up getting cheap accommodations for a small condo from an online agency and ski tix were cheap.. i believe $60 a day.. VT is a party town at least during the time we went but had a blast.. definitely blows local resorts here in the USA at $180+.. since we booked in advance flight wasnt bad either.. fly direct from LAX to Geneva and then caught a van transfer for 5 of us for about 200E. We spent one night in Geneva on the way in and on the way back.. i would say that was the most expensive part of the trip..
Definitely looking forward to going back there again sometime.
This is the view on top of Meribel, trying to find out way back to VT.
This is a spot my brother proposed to his wife overlooking VT..
