Sorry guys, I wouldn't say Disney's lines are "way longer" than any ski resorts - there are gondolas that run 1-3 miles up the side of mountains, and they also have mid-point stations as well. An example that I've ridden is the Whistler Village gondola - which stretches 4998 meters (3.2 miles if you convert it) and rises 3,800 feet from base to top. It takes 18 minutes to ride bottom to top, and has a 1-way capacity of 2,640 people with 8 person cars. It also has a mid-point stop - which is the location of the child-care service center - you actually drop your kid off at the base - and they heard the little ones onto the gondolas and up the mountain. So to say Disney's routes are more intricate than what is already done isn't really the case.
The big thing to me that Disney has that you don't see a ski areas is adding the capacity for wheelchairs and
ECVs. It's pretty rare that ski areas worry too much about mobility issues in the design of there ski lifts. I mean, yes there are people that are paralyzed that ski, but they have pretty good mobility.
