So I see measurements lining up this way based on that map: 8000 feet roughly to go from AoA/POP to CBR. Then 5600 feet to go to DHS. Assuming this completely separate EPCOT run, that would be the winner at closer to 9500 to 10,000 feet if it was to come in at the International Gateway. Yeah, I used Google maps, a ruler, and approximations for the tower positions to calculate the numbers, so there is certainly a significant margin for error.
I wonder what speeds we are talking about here. 1.5 miles from AoA/POP, at 15 miles an hour, is a 6 minute traverse. Then unload, move to DHS boarding, wait in line, get on a new Gondola, probably a 4 minute traverse to DHS. Going from CBR to EPCOT I'm assuming at least 8 minutes of travel time with the corners at 15mph. You can multiply all times by 1.5 if you think it tops out at 10mph.
What's the point of this? From AoA/POP to EPCOT it's 14 or 15 minutes on the Gondolas, plus wait lines and load and unload at CBR. How long does it take the bus to get you from AoA/POP to EPCOT? Google cites 21 to 26 minutes depending on where you are picked up (and avoiding those pesky things like loading
ECVs). So assuming your transfer and wait time at CBR is less than 5 minutes, and the wait for the first bus and the first gondola, and travel to the bus top and the gondola stop is essentially a wash, I guess this would save you a bit of time. Certainly would be more fun though, and I suppose that's the real point.
Before people start picking at my numbers, and feel free to do so, I'm not defending them. They are estimates on distance, WAGs on speeds, and unofficial data for buses. But it was a slow last few minutes for work and I was curious what I'd come up with.
