The upper deck is closed. Maybe you can ask them in advance if someone will let you up there.
I have heard that as well. I would suggest calling in order to get correct information. 305.480.1300. You can also reach the Marlins via email at ballparkfeedback@marlins.com. Let us know what you find out!
I was just there last weekend. Upper deck is blocked off and never saw anyone up there. I'm quite sure you would have difficulty gaining access. Maybe on a tour, though. . .
If not, I'd look at it as if it's not there. You can't buy a ticket and the capacity is like 29k without. I wouldn't even give you an asterisk for missing it.
