Planning my first Snowboarding holiday, any advice would be helpful!?

Renting is the easy part. Learning HURTS so bring pain meds. To save yourself lots of pain and possibly broken bones, when you fall back, roll with it. When you fall forward, use your whole forearms to catch yourself. If you don't, your likely to get a broken or bruised tailbone, broken wrist, concussion, or a MAJOR headache. Wear a helmet too. It helps a lot. Start off on easy, un-crowded hills. For clothing, you NEED waterproof gloves and snowpants of you'll be freezing. I taught myself to snowboard so It's possible but if you take group lessons, you could find someone to snowboard with while you aren't in lessons. This is just all the stuff I wish I knew before I started learning to snowboard. Sorry I can't help with the rest.
