We average about $20/night for our January to April Florida visit. That includes a 5 week stay at the Escapees owned FHU park near Bushnell, FL at about $14.50/night member cost, and a couple of NPS/COE parks at about the same with our Senior Pass. The rest of the time we're in state parks at about $25/night on average, with some full hookups and others W/E only. We stop at a few private parks for a night or two as fill-ins between reservations sometimes, but we do try to keep that to a minimum by back to backing the other reservations as much as possible. We budget $800/month for park fees, but rarely spend that much.
