I learned how to ride at creek, too. It's a great place for that. Are you going to be renting? I noticed the line to rent got really long around 11:00. I'd try to get there as early as you can.
I got my first set of snowboard as a Christmas present from the family, so I won't be renting.
I still plan on being there around 9 though, so I can get a few runs in before the majority of the people get there.
