Is your question really: "Should I stick to skiing in Austria so I have a good time, or stick to learning to board?"
If so, only you can answer that:
- Sticking to the board is the only way to learn. Sell the skis and you'll learn to board fast!
- On the other hand, if you've paid a lot for the trip and it'll piss you off if everyone's riding crazy terrain while you're spending time learning the basics, then ski?
