In reply to cas54321:
Im not sure why folks dont like chamonix for beginner / intermediate skiing. I learnt to ski there !
If there is only the Grand Montets open (and that does seem likely) the best thing would be to try and join in with a group lessons at the ESF. They'll take you places you probably wouldn't go and you'll have a good time.
There are blue runs on the Grand Montets. If they have been pisted and there hasnt been recent snow, the reds are not too difficult either.
I'll be there in April, and I know some people who think April is by far the best month of the year
My advice would be dont panic!
