Another concern is that this still doesn't solve a major connectivity problem for WDW... that the monorail system doesn't connect in any way to the Epcot/Crescent Lake/DHS boat and walking route, without being able to go through Epcot. It seems like if Disney built one more gondola station to the north of Epcot and adjacent to the Epcot monorail station, then it would also allow the gondola path to connect to the monorail route. Currently the only option is to walk through Epcot, which is a long process and a problem for anyone unable to get into the park.
And I know this has been mentioned elsewhere, but I'm still surprised Disney would build a system so easily affected by inclement weather. Even if other options are available. Combine with this the (probably) slow speed and it seems like a lot of money for less-than-optimal efficiency.
