With the Formula 1 at Miami, Florida this week, I came across the fact that the track has its own Dopplemayr gondola system called SkyView - check it out here: https://www.cbsnews.com/miami/news/hard-rock-stadium-gondola-dolphins/
What was most surprising was the price - 3M USD is bugger all for 12 cabins and an expanse that's 100m longer than what Sea World would need if you were to retrofit 1:1 the previous chairlift attraction (SkyView is 550m, Sea World's SkyWay was 450m-ish).
It's been long enough that it would probably be a drawcard for families again too - added to that, there'd be minimal site work needed and no real impact to the park to build. But here's where it gets interesting - if the park was to close the monorail, what if they did a loop system using gondolas instead? You could have two stations roughly where the old chairlift stations were, with a third station where the monorail station is at the resort - perfect for hotel guests, corporate events etc. At that point, you're only adding another 200m of infrastructure and a third station on top of the cost of the one in Miami.
What's everyone's thoughts? @Bikash RandhawaI think I solved your monorail problem - I'd be totally on board with this being a monorail successor.
