Just ask any CM at a transportation station. Last time we were there I took the ferry to MK one night to get a ferry card. I asked one of the ferry CM's and he said he would grab one for us ,came down during the trip and gave us a stack of all the boat related cards. I also usually ask as I get off the monorail and as we wait. As others have said its hit or miss as not all CM's carry them.
That sounds neat, but what exactly are transportation cards?
