Parking near Shadow Hills RV resort

I bought two shuttle passes for Shadow Hills because that is the closest to where we are staying. I just got the e-mail that you are not allowed to park at Shadow Hills unless you are staying there. Does anyone know if there is anywhere remotely close that you can park and walk to the shuttle stop? I'm trying to decide if i should try to swap passes for another stop.

Did you ever work this out? I wanted to do something similar for 2013 but I'm scared there will be no parking. Let me know what you ended up doing.

Thanks!
