But 3 busloads is 180 people. the Gondola system will take that in about 5 minutes. Remember a full bus is about 60 people. If capacity is 2400 people per hour (someone above said 4000-5000 but I think that is too high), then that's the equivalent of 40 buses worth to Epcot each hour, and 40 buses worth to DHS. Yes, it's four resorts, but there's no resort that gets 10 buses an hour.
And in the morning, you may get 2-3 buses worth of people, but those people don't all show up at the bus at the same instance, they arrive over time. The gondola will scoop those people up quick. I still insist the biggest issues will be
(a) park closure, or more specifically, nighttime shows ending, when you get that massive surge of people to resorts. As it is though, people get stuck waiting an hour for a bus, and it won't be THAT bad.
(b) weather events - while the gondola could maybe run during lightning storms, I question whether Disney will actually run them. If the gondola shuts down without alternative transport, not sure what the option will be.
The 4000-5000 number came from a reliable source on another site. They indicated that 5000 is the number Disney is shooting for.
