In the summer I belong to two membership parks, This lmits my parking choices but I pay on the order of ninty dollars a MONTH for parking, 2 weeks in one park, 2 in the other, all summer long... NOTE: area KOA parks I can easily spend 90 dollars for just one night.. Even the bargain parks in that area are in the 40 dollar range per night.
Where I winter I can only use one of those memberships so it's 2 weeks for 45/month (Plus I still have to pay the dues at the other park) and 12.00/night for the week out. YES, 12 bucks..
In the membership park I get 30 amps, Water, Sewer, Wi-Fi
In the 12/night parks 50 amps, water and a dump station.
I really LIKED that 50 amps last night.
NOTE: there is basically no limit on how long you can stay in this 12/night park.. You just have to change sites from time to time. Another 12/night park (For me 24 for many) 17 miles away you have a 2 week limit. that one is a COE park, same 50 amps/water/dump station. I get the lower price cause I have an interagency pass (Senior in my case) that gets me discounts at some federal attractions.. Up to 100% in some cases. Must be 62 or have another qualifying quality. (long list of qualifications for the cards).
I have stayed for as low as 7.50/night with the card in a Forest Service Campground.. Again 50/water/dump.
Lots of options. Many low cost.. NOTE that COE parks tend to be on lakes (Man made) or rivers. and Forest Service parks in some very nice, though remote, palces.
