Just being honest, based on past events at the Citrus Bowl, the Ubering-in is not a problem, but getting out is a bloody mess. Since the parking lots are not all controlled by the stadium, it is very haphazard where the entrances/exits are, and how you get back out onto the surface roads. Took me over an hour to get out of a one-square-block parking lot after the Guns N Roses concert.
Closer in time, I'll post information on the bus routes (not yet been finalized). Similar to how you could get buses between the MetroRail and the Orange Bowl, Orlando has been setting up free buses from near the basketball arena/soccer stadium to the football stadium. They used to pick up in front of the old police station (next to the basketball arena), but it is a construction site now.
If you are not taking tents/grills, then you may want to park near the basketball arena/soccer stadium, and either take buses, bike-cabs, or walk.
There is a lot of parking by the Florida A&M law school, and around I4 (both sides). The Orlando Magic parking garage is good too, it will probably be open that day.
