So the Dolphins plan to spend $3M on this project and Disney is spending 100X that? I know that’s an exaggeration and the Miami one sounds like only 1 station and a round trip ride vs 5 stations at WDW, but it still seems way less expensive.
It has to have at least 2 stations, even if you can't get off. Don't want guests whipping around 180 at full line speed.
Even those stations aren't the same as the Disney stations, probably just off the shelf. While the Disney ones are off the shelf with an entire building built around them. The route probably doesn't have to deal with anything special underneath it either. Just a sight seeing trip across the facility.
I hope they do not add light rail unless it is completely separated from car traffic, with overpasses and its own path.
That's really the root of all the options. Before you decide anything else, first you have decide if the transportation is going to leverage existing roads and mix with traffic at any point, even if it's just at crossings. If you decide that's the option, you can pick anything that can travel on that type of path. If you decide that there can be no interaction, now you have to figure out how to make the crossings without interacting.
My opinion is that they want the second option for new transportation, things that don't interact at any point with anything that's not part of the system. This means every crossing needs to go over or under the other item. Either raise/lower the existing road or raise/lower the new transporting option for the crossing. This makes all the grade level options harder, since you need to build grade level over and underpasses. Elevated options are easier, since they're already elevated. This also means elevated options have more route options, since the crossings hardly matter.
The gondola is an easy option of this. No interaction with a dedicated travel path, limited footprint on the ground allowing routes that pass over whatever mostly. Forced to travel in straight lines, requiring a station for turns is a big restriction.
A monorail has some of those too, but not others, just a different set of trade offs. One isn't "better" than the other, just different options.
