Moxy Sion is an affordable choice for a skiing stay in Switzerland, especially for points. We were there in January 2022. A short drive to 4-Vallee & Verbier, Anzere, Crans-Montana.
We often ski Val Gardena & do the Sella Ronda, and the surrounding ski areas, from the Four Points in Bolzano, Italy. A steal on points with 5th night free. The Innsbruck AC hotel in Austria is another good choice.
None of these are luxurious or ski-in/ski-out, but for a family on a budget they have been perfect.
