How is this "cutting corners"? Yes, this is less expensive them a monorail expansion, but it still provides an efficient way to move people around the property. If they wanted to be cheap they could have done nothing and let people to continue to suffer with busses.
They have the opportunity to expand the monorail system, a staple to the Disney brand, yet they won't do it due to financial concerns. To be honest, I would much rather ride a bus than a gondala. That's gonna be so awkward sitting in a confined space with another family besides your own.
