Hey Ed,
I live in Orlando, but travel a lot for work. I actually do more flying on the road than I do at home- Portland OR mostly. In orlando I fly at my church and a few other "Secret Sites" I've located, the city / county does not support or allow model flying in any public facilities I am aware of. this kind of puts a damper on organized flying in the immediate Orlando area. 1/2A would be easier to find a site for- less space needed, and easier to slip in fly and slip out before OPD / OCS show up.
There are C/L circles at the IRKS Field near Cocoa Beach, and at the Ridge Barnstormers R/C club in Lake Wales, both require either membership in the club or " Guest " status accompanied by a club member. There are also C/l fliers in the Tampa area and Ocklawaha. Look at the FOTO Op section and there are contact details.
Phil Coopy in Lake Wales and Roger Vizioli by Cocoa are the primary C/L flier / supporters I have flown with at each site. There is a fly-in at the IRKS field around Veterans day, info is posted in the Events section here. Phill hosts a C/L fly-in each year at the field by Lake Wales around Easter, both are well attended and a great time.
There are a few C/L fliers who used to fly across Tradeport road from the Continental hangars at OIA. They used the paved parking area for a building a bit north of the Navy Exchange store. They had to compete with the stick-ball players for use, and I don't know if they still fly there.
