Dave, done it loads of time skiing. The challenge you'll have is finding accommodation that runs over a weekend – eg if you need a Sat & Sunday night – always a challenge for self catering cos you're effectively hogging 2 weeks, so they clobber you for it. B&B gets round this.
Look at logis de france for b&b type options. There's logis places in Morzine and also nearby. We've used one on the shores of Lac Montriond which is kinda round the corner from Morzine, and very scenic. We used La Renardiere in Morzine when we did the ppds, and shared a room with 4 of us which was cheap.
The Morzine website is also good for accommodation….
