So I am not locked into Saint Gervais, just found reasonable transportation and a place to stay near the cable car. Can actually go anywhere within an hour or two of Geneva. With that in mind what would you recommend?
St. Gervais, Les Gets and Flaine are equidistant from GVA and the closest "real" ski stations. I have not skied Flaine but it has a lot of fans. I am most familiar with St. G as we were there two weeks ago, so what you are proposing (stay at the Monte Bianco hotel) sounds very doable. Les Gets is also good but I don't know the hotel situation there. As usual it will come down to snow quality, but if the weather is nice, a day and a half at St. Gervais will be really fun.
If you can get a bus to drop you off at the Bettex gondola base on Friday night and you can check in then, that would be ideal, and throwing in 2 day tickets plus board is going to maximize your time on the hill. For maximum efficiency, as I mentioned, rent gear at Claude Penz at the top of the gondola. Just walk out the door and go right. They have lockers in the basement where you can store your street boots. The first gondola up might be 845, so you'll be skiing by 930 or earlier. On Sunday afternoon you can drop off your gear and take the gondola down, grab your luggage at the hotel and head up to GVA. (If you can, wander into the center of St. Gervais -- across the river from the gondola) on Saturday night and get a beer or two. There's a couple of pubs near the church.
Earlier you mentioned that the St G/Megeve (or Evasion-Mt. Blanc) area seemed really big. It is, but the size is somewhat misleading. You won't be going to Les Contamines or the part of Megeve that's across the main road. Primarily you'll be skiing the bowl off the Mont Joux and Mt. Arbois lifts on the St. Gervais side -- the area is a huge U-shaped couloir with Megeve on one side and St. G on the other. the piste map is somewhat distorted. From the top of Mont Arbois, it's basically a ridge up to the top of Mont Joly. If you're going to ski Megeve I suggest Saturday morning, as you have to take a cable car across, and the slopes only get morning sun. If you go all the way to the high point in Megeve, at Cote 2000, it will take some up and down to get back to St.
The runs that face the town of St. Gervais under the Bettex-Arbois telecabine are also nice.
For on-mountain fast-ish food, Freddy's at the top of the ... Freddy ... lift is pretty good. It's actually right off the top of the Bettex-Arbois telecabine.
Hope it works out for you!
