I was wondering the same thing. It is always so much fun to get the family to sit down together and look at all the maps and talk about what things we want to do. It's been so long since I have been that my old maps are missing a great deal of things. I would love to have new maps of Disney and Universal.
They used to send out maps from Disney, but they must have stopped doing that. I did not see that as an option when I was looking.
If you can't find a DISer who'll send you some, you could also order them through eBay. The following link has maps for like 99 cents (plus 99 cents for shipping). Considering you'd have to reimburse a DISer for shipping cost, that's worth it.
