We stayed at Paradise Oaks RV Resort in Bushnell, FL last winter. We were there for 4 months and enjoyed the park. Friendly staff, friendly neighbors and a whole lot of activities. This is a newer well maintained park with grassy sites and concrete patios, excellent WIFI that was completely upgraded last year. Bushnell is about halfway between Orlando and Ocala and the weather tends to be moderate, temps in the high 60's and 70's during the day. We are returning again this winter.
Bushnell is near I-75 with easy access to I-75 and I-4. Here is their web address: http://www.theparadiseoaks.com/
