^ Doesn't seem logical to me.
I think if you can SKI and want to get some freestyle skills, then there would be no better place to go than a summer camp like windells. Irrespective of how good you are in the park, the camp would be a great opportunity to get solid coaching, learn new things, refine current tricks, get advice - whether that be a 180 or a doubleflip.
As said above though, the more you are willing to push yourself, the more you will get out of it.
