The single area passes don't exist anymore, which is good - e.g. if you get your pass in Flegere in the morning, you can use it in Le Tour in the afternoon.

For only 3 days on piste (not the Vallee Blanche?) you could either:

Buy a single pass each day and keep your flexibility. If you have internet access (there's plenty of free wi-fi in town) you can top up your pass online and avoid the queue - though you'll need a little bit of French as unfortunately theres STILL no English version of the login etc.

Or:
Get the three day Le Pass (no more messing about with getting them updated every day) and pay the supplement if you need to upgrade to the big one (Even if you're not going to do the Vallee Blanche, you might want to go up the Aiguille du Midi, and you may want a day at Les Houches, especially if visibility's bad or if the wind is high.)

I'd probably do the second one, it's easier, and with only three days, the less time in queues the better. Unless you're staying in Les Houches? Or intend to do a few runs from the top of Les Grands Montets ?
