In reply to Kaya:
You'll almost certainly find all the lifts and huts shut which could cramp your style somewhat. However, the Arco area should be fine as none of the VF need lifts or have huts. They're very different in character to the true dolomites though.
So, true Dolomite VF doable without huts/lifts - Brigadata Tridentina, Michielli strobel, Ettore bovero, Finanzieri Colac maybe?
Some others could be done in a long hard day - SOSAT, Piz Da Lech etc.
