I really hope they go with replacement monorails, but I fear they will go with Gondolas. The monorails fit in very nicely around the lagoon where I feel the Gondolas would stick out much more in this location (mostly due to how classic the monorails are to that specific area).
Of course at the same time if they do choose Gondolas, it would be far cheaper and probably run more efficiently so i'm gonna place my money on Gondolas
