I dispute nothing of what you say here. The only way a closed-loop system can accomplish something like this is with a relatively compact footprint...for example, within a a single airport campus interconnecting terminals, or as the monorail currently does around SSL. To try to interconnect every destination within the entire WDW resort on any single system becomes impractical, not only from a transit time perspective, but also economically, and saying nothing of routing challenges with various obstacles if the system is being retrofitted in. I'm in no way advocating for the complete abandonment of the bus system, nor am I contending that the Skyliner is the end-all-be-all. My only contention is that it is a good solution for interconnecting DHS, CBR, POP/AoA, Riviera, and Epcot IG.
