I cant recommend highly enough taking a lesson right off the bat. That way you dont have to unlearn bad habits you are almost guaranteed to get on your own. If you can afford it spring for a private lesson. Check out your local resort because some of them offer deals on private lessons at certain times. The other option is to book a group lesson mid day mid week and be one of if not the only one in the class.
Take a lesson. You will never look back and wish you didnt.
