I think monorails are cool but ultimately they don't seem to stand up as practical transportation. I will completely understand if it is removed someday from WDW.
I am happy with WEDway in MK and I would be even happier if they built one in Epcot, or built a monorail in the style of IOA's Dr. Suess ride. WEDway might be a better solution overall because of the continuous loading. Having to roof it may seem like an extra expense, however it's weatherproof and always comfortably breezy, and it could fit into Future World architecturally - especially if the existing monorail were removed, it would fill a gap and restore the look of the architecture and the feeling of motion.
AK needs a sky tram in the style of Busch Gardens Tampa. It's a great people mover, it's reliable and simple technology, it provides a 100 times better view of the park and animals than AK's current one-sided steam train to (practically) nowhere, and it would be a much needed relief on the feet when crossing the park.
