“The Las Vegas Monorail, which opened in 2004, cost $654 million for just 4.4 miles. It uses the same Bombardier technology as the Walt Disney World Monorail. Bombardier acquired the technology from Disney. There were some issues in Las Vegas—such as having to deal with many various property owners, structures in the right-of-way, and municipal politics—that Disney would not face. So maybe Disney could hold the costs under $100 million per mile.

A Monorail expansion would a be huge capital expense that would not generate direct revenue. Sure, Monorails could reduce bus fleet expenses. And, for guests, the Monorails add to the “magic” of a Disney vacation. But it’s still hard to justify the business expense, even if Disney could hold the costs to “only” $50 million per mile.”
