The main entrance has an area just for Joe Cool Club members and resort guests. Last time I was there, it was the far right entrance gate next to the park operations office. You should see a lot of people standing there waiting to get in as well as a C.P. employee standing near the end of the line making sure that you belong in that line. I assume that the resorts entrance by Soak City works in a similar way, but on a smaller scale. And you still have to pay for parking, although it can be refunded if you're staying at one of C.P.'s on-site properties. And from what I heard from standing in line waiting to check-in at the Breakers Express, the half hour early entrance ticket is only good for the following day, not for Friday night.
