Yes, and when there's a big convention this is certainly a fair point. But with Brightline being a private corporation, they need to know that there will be consistent heavy ridership along this line or why spend the money to do it? I think that's a reasonable question to ask is if it would have that ridership.
If Universal built a bus station outside of the Brightline station at OCCC and offered free transport from the OCCC stop on their own private land or county land, then I could see the line being more sustainable as Universal would have a bus connection at the station. But again, Disney will fight hard to try and make sure that doesn't happen.
