I'm there now 
Staying in 1650 with dd 7yo and ds 2 months, dh and other family members.
We hired skis from Francis blanc sports, it's next to the spar shop. Great service really friendly and helpful with my daughter.
Went to the aqua motion yesterday. Dd loved it, they wouldn't let ds swim as he is too young. You can hire towels for €5 each. It is really expensive but worth a visit, espacially if you have young kids who don't want to just ski. We walked down from the village but the escalator is only a short walk from the pool. Wish we had known before we walked all the way down but at least we were able to get back up easily.
Dd has been having lessons with sweet ski and snowboard. They have been amazing with her, she is asd and really struggled with skiing last year but has got so much confidence from only 2 lessons, she is going venture off the nursery slope tomorrow, never thought she would do so well and pick it up so quickly. She def has the bug now!
We are in a catered chalet so are only eating out tomorrow night, we are going to try portetta which is just along from where you'll be staying. Will let you know how that goes.
Second other reviewers, it is so expensive here, try to get food before you arrive at the resort if you can. The snow isn't great at the moment either and quite patchy in places. I'm pretty sure some runs will have to close in the next few days. There is more snow forecast for next week so hopefully conditions will improve for you.
Sorry for the long post, hope it makes sense, am sat typing on my phone! Hope you have a brilliant time, have skied in several french resorts, also Austria and Switzerland and this has to be one of my favourites
it's just got such a lovely atmosphere.
