Looking for advice on Chamonix

I don't think beginner, intermediate can get bored with weeks skiing in Chamonix. I would argue that les Houches has the nicest piste skiing in area when snow conditions are good. Some great runs and also best mountain restaurants in the valley.

Flegere some really long reds from top lift, perfect for just linking turns. If you can go top to bottom of that then serious burn in legs.

Argentiere, for onpiste I do not believe is a great area. My favorite is the run back down to Argentiere. Best skied in the morning when nobody else is on it. Nice run off the Hurst as well.

Balme, plenty of easy blues, nice and wide and normally quite so good for working on high speed turns. Auguillette is perfect for this.

Brevant is my least favored of the 5, don't get lured into staying there on basis is closets to town. Others are worth the trip.

If you have a car then St Gervais etc also comes into play.

Basically more than you can handle in a week.

Thanks again to all those who have contributed advice & info in the true J2 manner, On the overwhelming positive nature of the comments I have told my daughter to book me in for the trip. :-)
