Replying to Frisco - Copper Shuttle

My plans got messed up and long story short, I don't have a parking reservation to ski copper this Saturday. Is there anything preventing me and a couple friends from riding the shuttle from frisco and skiing without parking? Does anyone have any insight into whether that's been crazy busy or not?

Additionally, might be skiing with a couple more who will be buying day passes. Will they be fine to shuttle and buy passes at the window?

P.S. I have copper parking for next Saturday, the 19th and would love to trade if anyone's got one for this Saturday, the 12th.
