In all fairness, this is something that I am now wondering too. What I'm curious about with the Gondalas when it comes to selling point, perhap's its a way to add a mode of transportation to a park (and multiple resorts) that doesn't have a legitimate monorail stop?
Excluding Epcot of the picture, DHS; Animation; and Carribbean doesn't have monorail stops, and uses the bus transportation to get people to and from the property. Perhap's this is just a way for them to add an alternative way to get to certain parts of Walt Disney World?
