Port Richey RV Parks
Some are in New Port Richey, some in Hudson, some in Port Richey; all three towns all run together. Those off Little Rd (rather than on US19 would be better for traffic, IMHO, and are just as convenient.
We drove thru Orchid Lake in NPR and it seemed pretty nice with a lot of long term residents.
ETA: you might have to take what you can get. Although Port Richey isn't exactly the "hotspot of tourism" in FL, we do have lots of snowbirds.
