When you first enter the Cardinals camp, you only have access to 2 fields, then have to walk around another field to get access to 4 other fields. There was very little security/people to ask where to go (I'm comparing this to the plentiful security guards at Tradition Field), and it was more just follow where everyone else was walking.
After taking a trolley back to the Marlins side, there is one entrance and it opens you up into 4 fields, with a walking path to another 2 or 3 fields all in close proximity. Pitchers were working on PFPs (pitchers fielding position), as well as bunting on 2 other fields.
There was no BP going on, nor any bullpens being thrown, so not much to report on skill-wise.
The biggest contrast between the Mets & Cardinals vs Marlins camp is the lack of fans. There were probably 10 fans there for the Marlins. The players would walk on the same path as the fans, and make eye contact, practically begging you to recognize them.
Here is a couple pictures from the workout:
And my favorite picture of the day, courtesy of the Marlins player's parking lot (anyone know who's car is this?):
