Is there Age Limits on TT to stay at Current Parks or CG???

We stayed at a place in Destin, FL (Destin RV Resort) that had a 10 year age restriction, but also had a clause for "vintage" and "Airstream" models. If you were over 10 years, you had to send pictures to them, then you were approved or declined. The place was very, very, nice though, cobblestone streets, highly manicured flora, etc...
