You might want to take a look at Hollywood/N. Perry KHWO north of MIA. Four runways, two NS and two EW, with an operating tower. There are
several flight schools on the field, but no idea as to rentals. Try ATA, run by Mike Punziano who is president of the local chapter of the Florida Aero Club, a get together social organization. APA is a recent start up run by Bob Diaz. You can Google ATA and HWO for information.
