Has anyone here used these? They're for special parking areas at the parks, you still need to pay for parking though. I was given two passes today when I bought my tickets, and thought that one was all I needed. I think they must take the ticket, or part of it when I enter each park. If this is so, which two parks would parking close be advantageous? AK, MK or Epcot? I'm thinking MK for sure might be closer, but if anyone can confirm would really appreciate it. We leave Friday!!
