All DLR has on their site are print-at-home maps. The ones at WDW are "fancy", way too big to take to the parks, and not quite detailed enough to really plan with (IMO).
I have some DL maps from the parks in March; if you'd like one, I can mail it to you. I don't have any DCA maps, though. But if you want the DL, pm me with your name and address and I'll get it in the mail as soon as I can.
