Outdoor Resorts of America (ORA), Melbourne Beach, FL. The lots are individually owned however, can be rented through management company. I think $35 or $40 a night, not sure on weekly or monthly rates. One side on ocean the other on the Indian River, fishing pier, three pools, etc. - all roads paved, golf course ¼ mile, many many activities through April. Diane Graham is the manager, 321-724-2600. They have lots available; we were just there three weeks ago.
We liked it so much we bought one…but still working, visitation only.
