How do you do it? I was lucky enough to have one mailed to me, and I thought during my trip in a few weeks, I'd see if I could accumulate some to send. Do you just ask for one every time you enter a park and put them somewhere safe?
As others have said the maps and schedule for the week are right at the entrance gate for each park.
You can pick them up there as you go in. What I like to do is grab a stack as we're leaving the park to go back to the room for a break.
This way I don't have to pack them around and they're in better condition to send out.
