Sup Hidde! I would kill to get to ride some of the places your going to get to, lol. The DJ'ing sounds pretty cool, good luck with that!
As far as your question about learning, most places here in the states I read about have half and full day lessons. From what I understand, thats usually enough time to give you the basics and allow you to go work on and hone your skills on your own, if you were'nt standing off to the side taking pics, picking your nose, etc.. :P I have also had several istructors tell me a good instructor should be able to give you a decent lesson in around an hour, possibly even less.
Good luck to you man! I'm a newb myself, and just got done purchasing my first board w/bindings. Hoping to hit the slopes for the first time this next month.
Stay safe out there...
