There is no RV parking at the Marlins Park garage. I would go to a local RV park and Uber to Marlins Park (or use the bus or whatever. )
The best answer for this questions about the Marlins park will be calling directly to their customer service department. I have never been to the Marlins park events.
I wouldn't even if you could. The traffic during an event is horrendous.
Not
Not sure, call
