If you cannot take the Creek lift line, then this sport is not for you. It does not get faster than that gondola. I am usually good for 18-22 runs in a day at Creek, there have been days at Highland that I got five with the same type of push for runs. Plattekill/Thunder/Blue 8-10 on busy days.
Question - do all of these parks typically let you ride to the top if you so desire? I believe there is a way to get to the top of Creek by pedaling but you kinda need to know the place and of course actually pedal up. 5 runs in a day seems absurdly expensive to me. I know pedaling a monster bike uphill isn't exactly fun but then neither is paying this much to stand in line all day.
