In reply to FreeloaderJoe:
I usually go on my own and do both chalet and hotel based holidays. Chose a ski company that offers an "ambassador" or similar "get to know the area" service. You can chose a group of similar level skiers and go out with them. This way you will quickly meet a nucleus of people of similar ability and generally like minded people.
Otherwise go for a dedicated singles/solo holiday. Most emphasise that they are not a dating agency, just a means of allowing solo skiers to meet.
