Grand Lake in Orange Lake Florida, just a bit noth of Ocala is a good choice. We stayed there for a week this past spring. Staff seemed a bit apathetic, but it was toward the end of the season so maybe that's why? Nice 9 hole golf course with great rates for guests. Perfect choice if you are a golfer. We also stayed at
Wilderness RV Park Estates in Silver Springs, a bit east of Ocala. This park is gorgeous - especially in the "preserve" section. Extremely reasonable rates, particularly considering how nice the park is. If golfing is not a huge priority, I would highly recommend checking out Wilderness Estates.
