Brightline knows there is money to be made connecting MCO to Tampa, but the cost of borrowing the money to build it is dramatically higher now than it was when Brightline originally began planning it. Once you factor in the cost of construction and debt, even something with really high ridership may not be worth building. Being able to build this stuff for a reasonable amount of money is crucial if you want it to actually happen.
Unfortunately for everyone except a few dozen people in Hunters Creek, it looks like the cheaper option is off the table. So now we are at the mercy of the federal government, the state of Florida, Florida's Turnpike Enterprise, FDOT District 5, Universal, the voters of Orange County, the counties of Orange, Osceola, Seminole, and Volusia to come to an agreement. I'm not saying it will never happen, but it's odds are low.
