It took me 3-4 days to pick up the basics and be able to reliably get down easy/intermediate runs without busting myself up. I had a skiing background, but the people I know who didn't picked it up in about the same amount of time.
You'll fall down a lot the first couple days. If it's icy you'll be banged up for sure (my 2nd day was wild icy and I was bruised to hell the next day), but if there's fresh snow, falling down doesn't really do any damage.
