The monorail wouldn't be faster if it ran to every park and resort, big guy. It would actually be a lot slower, with those tons and tons of stops on the way. And they'd have to run one or two total lines, because otherwise you'd have too many transfers, and the more lines you have to run, the higher the cost goes.
And that doesn't take into account the multi-billion dollar investment that creating a complete property monorail system would cost.
Really, what do you think is a better idea. Spending $2b+ on a non-efficient way to get people to the four parks, or spending that money either on a new park or upgrades to the existing ones? And don't forget, you also need the monorail to go to everything else. DTD, TL, BB, WBP, etc etc.
Note that I'm saying non-efficient because of the way it works, not because the monorail itself isn't efficient. The biggest inherent problem with the monorail is this: You cannot quickly and easily add a train. And the guest flow for the property doesn't work well with anything that is on a set track. You have big crowds at certain times, and no crowds at other times. Can you imagine the MASSIVE line that would exist to get on the monorail after closing at MK, if all resorts needed it? It would be insane.
And I'm just touching the surface of the problems with this post.
Monorail expansion is such a terrible idea, it really isn't even funny.
