We are owners at
http://www.rranchga.com located in north GA mountains. We host Passport America and Coast to Coast on a basis of selected blackout dates and limited stays. The REASON is simple. We have "owners" who only use the resort on selected dates and come in from all over the country. The ranch is required to have space for them as a priority.
When we travel, we use GS or KOA and never have an issue. I use campgroundreviews.com as a sounding board and make my own decision and ride with it.
Going to AZ for the winter. Fortunately I have a friend in Mesa and he visited the campground we reserved and confirmed all the reports as positive.
Lots of choices out there......Just went to FL for 2 weeks to see the last shuttle. Spent 1 week on the ocean and 1 week at The Great Outdoors RV Resort in Titusville. In Jacksonville we stayed at Hanna Park (city owned) full hookup for $32 a night. South it was $45. Room in the 5er was clean and comfortable and NO BED BUG concerns
