We went in Jan 25 and the snow and weather were amazing. Les Menuires has the best access to each of the valleys, we managed to ski to the far ends of the 3 valleys over a few days and still make it back before lifts close. and there's a good selection of runs in Les Menuires itself. Lifts are quite efficient at the bottom of Les Menuires. As with all resorts, runs at the very bottom of the valley like the fontanettes and where the Menuires meets La Violette get busy, so they can be hard if it's the first time you're skiing/snowboarding.
