In WDW there are books for purchase (for kids, I guess) which get stamped at different spots in the parks. In Epcot, for instance, each country has a rubber stamp. Is there anything like this at DL?
Disneyland has done something similar for special occasions (i.e. the 45th Anniversary map, the 75 Mickey Statue pin hunt) but they do not have a regular program like the Epcot passport book.
