Greetings! There is one course in Port Charlotte, but its pretty cool. Most holes have two sets of tees, and/or two perm. sets of pins. There is a local league, and a few local tournaments. Sarasota has a well established scene with a couple of nice courses, and a long running league, and awesome events. The Ft Myers area is an emerging scene, with some nice courses, etc.
The Tampa area has the biggest density of courses in this part of Florida, from old school city park style courses, to longer more modern style DG dedicated courses.
The courses down here are a little different than the ones up north, but there is some good disc golf to be had. Hit me up when you get down here, and I'll be happy to guide you around, show you our courses, and fill you in on the local info.
