> La Rosiere?
I've been to La Rosiere/Les Eucherts I think four times now, with friends, because they like it for the kids. LR has a drag lift to the right, coming out of resort (as does LE), which leads to a lot of nice greens, and some fun paths in the trees for the kids. LE has a covered moving carpet for real beginners, and the drag leads to a short beginners run. Both have reasonably easy blues back from the main chairs out of resort.
The Fort area is mostly reds, Blanchot and Marmottes being my favourites, and there's a lot of piste-adjacent stuff to play in. It's also easy to get out, have a good ski, and come back to pick the kids up at lunchtime. Some of the lifts are slow; Fontaine Froide and the very bottom of Marmottes especially.
The piste adjacent bit coming back into LE was perfect for just one bright day this year; lovely powder that had me literally whooping with joy as I came down through the trees. And I'm a cautious skiier who isn't great in deep snow. The next day was a complete whiteout, and we saw a poor snowboarder out of his depth in the same area, slowly bum-hopping a giant trough about 100m down the slope; a complete change of character overnight.
It can be a miserable schlep to and from La Thuile. With beginner kids, don't bother.
It can be a bit cold. Or maybe that's just been timing and bad luck.
We've stayed in a small SC apartment block 'La Refuge' a couple of times, which is very nice, and fairly close to lifts and shops, and just about possible to ski back. We booked through the local tourist office (lift passes included in deal).
