In reply to IMA:
I went to Cham last year for a few days on my own.
To be honest it was a fairly miserable experience and I would avoid doing it again.
I found that the vast majority of people were with friends/family and weren't that keen to extend that to a solo traveller which, to be honest, is fair enough. Would you want someone you've only just met tagging along when you're skiing with your girlfriend? Those that were alone lived locally and were quite content to get out for a couple of hours and then go home to their own friends and family.
I also found piste skiing alone a fairly miserable experience - you get loads done but there is no-one to share it with so it becomes a bit repetitive - lift up, ski down. Repeat. There is no waiting for people halfway down, stopping for a brew, laughing at wipe outs, trying ridiculous drop offs with mates etc etc.
I suspect a course or lessons would help as you would get to know people during the day and I would do it this way if I went solo again.
