The training faciality and TD Ballpark are at two different locations right?
While looking for that answer, I found this site that has a couple of awesome, longer videos showing all the improvements.

TD Ballpark capacity increased from 5,500 to 8,500 - new air conditioned bar down the right field line, new 360 degree boardwalk around the outfield. This is awesome. I wasn't fully aware of all these improvements. I've been to Dundin a few times, and to many other stadiums in Florida and Dunedin's was always one of, it not clearly the shittiest. This is now reason to make the drive up (2 hrs) to show my kids.
