In reply to AdamDawson:
Been spending some time recently in the Monte Rosa area & the area of choice to stay for most people seems to be Gressoney for the reason mentioned by Jon, ease of access by car from the Aosta valley.
If your coming over the Simplon pass though, Alagna can be reached eventually, with the lift right in the center of the village. Be warned though, its very quiet which obviously adds to its charm, with no supermarket, only two small shops & no Chamonix style climbing shops.
There are camp sites coming up the valley in the various villages that you travel through & one in Alagna as you enter the village & obviously great pizza, bars, associated restaurants etc all so much cheaper & better value both in terms of price & quality than Chamonix.
Have fun, its an area I'm just beginning to explore with lots of very quiet areas, valleys, bivi huts in which to acclimatize before heading up to the Gniffetti refuge
