Lots of great accommodation all over the place! For chalets, I've stayed in 3:
1) Meribel Village:
Pros: Quiet, LDV is a GREAT pub!, most accommodation very close to the "Golf" lift
Cons: "Golf" lift is slow and gets you to the bottom of "Altiport" lift so a bit slow up the mountain. Many operators will take you into the Chaudanne first thing in the morning as it's quicker.
2)Meribel Mottaret:
Pros: More potential for ski in/ski out, Cheaper than Meribel centre, easy access from almost anywhere on the piste map
Cons: As mentioned, not that close to Meribel if you want a night out although there are OK places to go in Mottaret, very flat green run through Mottaret into Meribel could be annoying on a board
3)
La Tania:
Pros: Lovely village, quiet, good places to eat, sunny, quite a bit of ski in/out, quick access to Courcheval and Meribel
Cons: Harder to get into and back from VT in a day as you need to get through the Meribel valley, not much nightlife.
However as many have said the 3Vs are fantastic, look at where your accommodation is with reference to a piste map and work out how easy it is to get to all 3 as that's the key!
