Suggestions for staying down the mountains and travelling up each day

The resorts around the Valais are offering a Valais ski Pass this winter (I think they trialed it last year). From their description:

The Valais SkiCard is a hands-free lift-pass that works on a prepayment system. It can be used for all ski resorts of the Valais, most ski areas of Vaud and some resorts in the Pre-Alps of Fribourg. It also gives access to the thermal baths of the Valais and the Gianadda Foundation in Martigny. Valais Skicard holders can charge their card with a desired amount of money without having to queue at the ticket counters. Acting as a cashier, the pass scanner, registers your age and price category and automatically deducts the exact amount from your Valais SkiCard each time you go through the control gate.

In theory, you would be able to stay down in the valley somewhere cheaper and try out a range of resorts. Has anyone actually used this?

Downsides are the obvious ones of having to drive somewhere every day and less obvious one is that I'm not sure how much cheaper valley accommodation would be. But I'm not sure about the

My kids have used the Valais Ski Card for several years (I think they first became available in 2003) with no problems. I just top them up at the start of the season and they can access any ski area in the region apart from those in the Portes du Soleil, which have a different ticketing system without having to go to the ticket counter.

Bear in mind that day tickets work out much more expensive than weekly passes and there will always be a residual amount on the card at the end of your holiday which expires after a year unless you top it up again.
