The discussion was about how to manage large numbers of people exiting the parks. And related to this mentioned that the gondolas held a limited number of people and only served 2 parks and 4 resorts.
My point was that the gondolas would get up to a third of the guests at those two parks "home" far far quicker than any other form of transport. Thus releieving the problem immeasurably at least at Epcot and DHS, allowing more buses to be deployed for people staying at other resorts. Most people staying at CBR would be home before any of those at the All Stars.
If you think of Epcot, add on the BWV, BC, YC and Swan&Dolphin, and you could have up to half the guests leaving from the IG. That will make a huge difference to the numbers at the bus stops, with more buses free to pick them up.
