In reply to aostaman: I've booked two trips next year and on both occasions have booked a self catering property and then a chef to come in and do chalet type board:
http://www.thechalethostco.com/prices/ - so around £30 a day for half board.
Self catering we booked a 5 bed place for about £1200 for the week, so we just split that between however many are there (people are coming and going, some doing a full week, some a shorter break).
Alternatively Dougie at morzineskiholiday.com is great value at about £65 a night including transfers.
