FLORIDA DARK SKY SITES
I made the animation below from 2012 NASA/NOAA Suomi NPP satellite images, and I overlaid a map from the USGS. There are some differences, but it's as close as I could get it without radically messing with the photo, and I needed to use a map in the public domain for copyright reasons.
The image below is cropped from an image featured in a a recent 2016 science paper The New World Atlas of Artificial Night Sky Brightness. White represents the brightest light pollution areas, blue the darkest skies.
This map is based on data published June 10, 2016 by a team of researchers led by Fabio Falchi and including NOAA's Chris Elvidge and CIRES' Kimberly Baugh.

This image is a composite assembled from data acquired by the NASA/NOAA Suomi NPP satellite in April and October 2012.

Some Known Florida Amateur Astronomy Locations:
Big Cypress National Preserve - off of Tamiami Trail East (also see Kirby Storter Roadside park below for another Big Cypress Preserve location.)
Chiefland Astronomy Village Many neighbors team up at this location to provide one of Florida's most amateur astronomer friendly locations, and they host monthly star parties, and usually a major public star party in the Fall.
Fakahatchee Strand Reserve (a.k.a. 'The Fack'), off I-75 - touch base with someone at Everglades Astronomical Society to see when they're out there or see their calendar.
Farrout Observatory, Dade City, FL "Where Tampa's Astronomers Cluster"
Kirby Storter Roadside Park - It's surrounded by the pristine Big Cypress Preserve. Here's a google maps link that shows it clearly too. See this 'street view' to see the site!!! Looks like it's free too.
Kissimmee Prairie Preserve -not in Kissimmee, listed as a Silver Tier Dark Sky Site by the International Dark-Sky Association in 2016, it is also the only IDA certified International Dark Sky Park in Florida it has astro observing sites too, check with them for info here at this link http://www.floridastateparks.org/kissimmeeprairie/

Osceola National Forest site of NEFAS (open to all)
Biolab Boat Ramp Site near Canaveral National Seashore. Get permission before observing at this site (or you'll likely have a short session, as I did :^). This is a wonderful dark sky site.
Shired Island in Dixie FL
West Summerland Key/Camp Wesumkee - Site of the Winter Star Party
Withlacoochee River Park (county park with fees) - see http://www.stpeteastronomyclub.org/viewing.php for more info.
