If you can tolerate slightly cooler temps (40s-50s nights, 65-80 days) there is a real bargain park just north of Crystal River. It is an ownership park and each owner sets their rates, but most are asking $350 -$500 monthly for winter season, some including electric. Some owners will rent by day or week. Various size lots from standard 40x80 to huge. Nice gated park with screened and heated pool, very friendly to renters, has dog park, abuts a state bike trail and boat ramp along the FL barge canal, can bike 4 miles to the gulf. Take note: No cable, and Wi-Fi available only at the clubhouse. Lots of rivers, fishing, kayaking in area, more 'old Florida' atmosphere. You can check out the video on the home page, then click on the blue star to see rentals availability, rates, photos, and contact info for the individual lots. Doubt you will find a nicer park at rates this low.
