I mean, as to what everyone has been already stating, I feel a monorail-type transportation system is necessary and fundamental to their expansion plans. How could you not when you are gaining over 400 acres of new land? For the resort to have a cohesive, unified and connected park, it is 110% worth the financial investment to get it done right the first time. In my mind, relying on Buses, especially along that strip, would cause havoc and I feel like local businesses would be a bit annoyed with the increase in traffic.
I mean think about it....if universal has maybe 8-9 million visitors a year to its current parks(whatever it is), that comes about to roughly 28,000 people per day. not taking into consideration of the many variables such as peak dates, there definitely is more than 28,000 people on the resort at a given time I'd think. Say the average coach is 50 people...that would be 540ish bus trips a day on I-4. Now think about about 400+ new acres and the increase in attendance. It just logistically, financially and environmentally makes sense to not rely on buses.
I know that analysis is very loose/not statistically 110%(as its late), but you get my point
