Anyone who's wondering.. It took us roughly twenty minutes to exit the parking garage after the Cubs game.
I recommend (if you're coming from the North)
To bypass the dolphin expwy and get off at SW 7th, come in from the south. Lot less traffic
Tried that once and didn't like it. Now we get off at the airport exit (112) to 22nd Ave. Barely any traffic. But that was on a Saturday.
That's the thing, you probably need to try it several times to get a good idea for how the traffic is with the new occupants of the Orange Bowl site. Now that the Marlins play 81 home games things will be different than when it hosted college games every so often.
I know I got a little lost going to look at the site when it was under construction last year, so I can imagine it would be a nightmare for me looking for parking on gameday with everybody else competing for parking. That's the one big thing keeping me from attending. I'd rather pay some bar for a seat on a party bus from Broward and just not have to worry about it at all.
