FLORIDA OBSERVATORIES (many have public viewing nights, check their websites for details)
Belen Observatory at Belen Jesuit Preparatory School, Miami
Crosby Observatory at Orlando Science Center - 10" Refractor - admission fee to Science Center.
Eastern Florida State College Observatory - 24" Ritchey-
Chrétien telescope available for public viewing Friday and Saturday nights from sunset until 10 p.m..
Egan Observatory at Florida Gulf Coast University - 16" Ritchey-Chrétien telescope and 5 smaller computer guided go-to telescopes.
Here's a google maps satellite view of the observatory dome, and here's a link with more info about the observatory. Public access through Southwest Florida Astronomical Society.
Embry Riddle Creekside Observatory - They have a 20-inch reflector Dall-Kirkham telescope by Planewave Instruments , three 12-inch reflectors, a 4-inch refractor, and a pair of giant binoculars and a new observatory with a 1 meter Ritchey-Chrétien telescope (see images on this page.) Free public viewing open houses are to be held approximately ~6 times per year. During open houses there will be a public lecture at 7 p.m. and observations from 8 p.m. to 11 p.m. During open houses there will also be additional presentations such as Gravity Well Simulator, Solar System Tour, Space Posters, and a Photography Gallery. Amateur Astronomers will be also be invited to set up telescopes outside for public viewing.
The Embry-Riddell Telescope is the largest public accessible telescope in Florida with a 1 meter (39.4") primary mirror, a 40 cm (15.7" secondary mirror), with an 8 meter focal length (f/8). The primary mirror weighs 700 lbs, and the total scope weighs 5500 lbs (not including the massive 6 story pier that it sits on that is separate from the building!) The largest refractor riding as an outrigger scope is an 8" APM. There are also a number of other outriggers that are Takahashi's and Vixen.
The Student control room can be seen in one of the images below (which is not the same as the local control near the scope, and I've got a shot of the Infra Red dome surveillance cameras too.

Florida Southern College Miller Planetarium - Lakeland, currently closed, and their website was taken down in 2014 (after they had been closed for several years.) They are trying to get funds together to re-open it, possibly within a year? Their structure is the only observatory in the world designed by the famous architect Frank Lloyd Wright, and was founded in 1959.
Florida State University Pat Thomas Planetarium - Tallahassee

Here's the public-accessible 10" refractor telescope at the Orlando Science Center. The operator says that this was Mr. Byers last 10" refractor (the optics were also by him.) There is significant vibration from the surrounding visitor floor (even though they tried to isolate the pier from the gantry.) People can access it on clear Friday and Saturday nights (when visiting the science center with paid admission, however there are sometimes ways to get significant discounts, up to free access.)
Above you can get a sense of how high up the new 1 meter telescope is at Embry Riddle in Daytona, Florida (my estimate being around ~6 stories.) Photo by me on 7 July, 2013.
Notice how the giant telescope pier directly under the dome angles off at the last level of the new Embry Riddle Observatory..
They are installing the windows to the left as of 7 July 2013.
This is the amazing massive pier to isolate the new 1 meter telescope from the building being constructed around it.
Miami's Stocker Astroscience Center at FIU released a video showing their new facility, 24" telescope and mentions their star parties and 4 remote telescopes around the world.
