I think the real issue will be capacity (and YES, I know many of you claim to have seen throughput numbers) but those of us that have used these systems at ski resorts know a few things:
1. It takes time for people to get on and off of Gondolas. Even athletic people. When you are dealing with older people, families, little kids, strollers, etc., you are going to have some very slow people taking their sweet time getting on and off. Ten second dispatch? I really really really doubt that....
2. I realize these things seat 8 people BUT they will not separate families and "grouping" will be challenging. Paired with a desire to load quickly and I think many gondolas will go out with empty seats.
At ski resorts (and people have their skis OFF before they load the Gondola) long lines, slow moving lines for these systems are COMMON. The line will only move as fast as EACH group moves. One slow group will slow down the entire line. Watch and see.
IF long lines happen, then you will definitely see efforts to reduce demand through limitations on who can ride and when. It doesn't take long to install a Magic Band reader!
Before you comment on "oh it will be the same as ever" and "there will be TONS of capacity except during very peak times" I'd ask you to comment on whether you've experienced these systems at major ski resorts where a) athletic people hop on quickly and b) far fewer people are trying to board than will be the case at Disney, and c) observed the lines....
