Yeah, you can rent snowboards there. I assume you're a skier or have you just never done any snowsports?
Either way, if you're going to try to make a determination on it over the course of a weekend, at least do yourself a favor and get a lesson. Expect to flail around mightily. Expecting anything else will be setting yourself up for disappointment. When are you going? This weekend? If so, I suggest sticking to skiing if you're already a skier. There's just too much new snow not to take advantage and enjoy it to the fullest.
