Look at the activities offered. If they are geared toward younger or older retirees. The size of the park. In camp or outside of it excursions.
We know parks from Fl. to Ca. we would love 10 yrs from now, others we felt old at 10 yrs ago.
Weve been dissatisfied, and happily surprised. 55 + is mostly a reference, same as a 10 year old rule. If you are a grown up empty nester with a good unit, you do not have to prove your age, or that of your unit. Dont lie, just dont tell. They dont check your vin # or birth cert.
We also use Rvillage.com to connect with like minded nearby others to put together a 4some for a dinner, golf, a fishing charter,
Dont choose on low price. You get what you pay for.
