OK so as an update, having a think about Skiing in the Aosta Valley for this trip. Quite fancy basing myself in Aosta, having a hire car and doing a day or 2 in Pila, Courmayeur, La Rosière, a day up in Cervinia etc and possibly discover some other little gems along the way.
Couple of really cheap hotels knocking around in Aosta, car hire is £150ish, and lift pass at £248 covers all the ski areas. ATM its coming in at £770 for me on my lonesome, flights, passes, car hire, B&B for 2 people it would work out circa £645, and so on.
I'm getting some people together for Tignes New year's eve week this year. We'll be staying at the UCPA there, everything all in comes in at £761 if you book before 31 Oct! This includes full board, 6.5 days Espace killy lift pass that cover Val d'Isere too, 6.5 days ski/board, boot, pole hire and half time instruction. Their equipment tends to be so good I don't bother lugging my skis.. plus, if snow cover isn't great I don't have to worry about wrecking my own stuff. We book via action outdoors and our group can be found here: www.action-outdoors.co.uk/holiday/cart?GroupRef=dc5d506c
