I think they should the elevated lightrail system that is in place in Miami. It Only needs columns. It could go from one resort to the other making a stop at the former Wet and Wild hotels. It could end at the end of the convention centrum making every Lows hotel at universal an easy expansion for the convention center and every hotel a convention hotel.I wonder if they could run a trolley (street car like in New Orleans) down the middle of Universal Blvd from the WnW plot down toward the Convention Center.
It was a few years ago when I stayed at the Orlando Hilton while visiting UOR, but I seem to recall thinking there was a lot of unused land near there, then driving to UOR via Universal Blvd and thinking there was room for something like a street car in the median...but I have no idea how much space something like that needs, esp if it would need to be two tracks....but I do recall it being a rather easy drive.
On the theme of the parks (I bet there will be 2) is already thought when they bought the land the first time. Good ideas never die at universal, they only get better.
