First I would like to make clear that I love the idea of the gondolas. I think they will be great. They will be a thousand times better than buses and more efficient than my beloved monorails. I do no think they they need AC as the flow of air when they are moving for the short distance they travel will be pleasant enough. But as I have thought about all the situations that could occur only one issue kinda scares me. I don't think it will happen very often but when it does it could be really uncomfortable. At some point every long once in a while the system will stop for some situation that could leave you sitting in a gondola with 7 other people, on a hot summer day, in the direct sunlight, on a day with no breeze. Lets say it takes 10-20 minutes to start moving again. How hot will it get in there? Lets say that hot, breeze less day that your stuck in the direct sun is the one day in the decade they have to evacuate the cabins and it takes hours to get to your cabin. How hot will it get in there? I've only been in ski gondolas on the mountain in the winter (lots) and a large one in Hong Kong in the summer all of which have windows you can lower. If the Disney ones only have vents and no windows that open, I could see it getting uncomfortably hot in these very rare situations. Thoughts?
