You have to be careful on a lot of these camping clubs...many have "restrictions" or "black out" dates that you cannot take advantage of their "special pricing". I was a member of Camp Club for two years and never once was able to take advantage of their "50%" off rates. Always the wrong season (some of their camps are only pre-season and post-season) or the wrong day of the week, or too short a stay or too long a stay or doesn't apply to full hook ups...they have quite a list of "not good for" reasons.
The way we travel, "sight seeing", puts us in popular areas for tourism frequently, even the more "out of the way" sights. There are plenty of campgrounds to choose from and they don't need to "give away" half their rates to entice people to come and stay with them so we were never able to take advantage of their discounts.
That being said, many people find the various groups advantageous to the way they camp and do quite well with them. Your best bet is to plan an imaginary trip and then go to one of their websites and look at the member campgrounds and restrictions for the areas you'll be in. That will give you better insight into exactly how they might fit your traveling style.
The only "clubs" that I've ever gotten reliable, day in, day out, discounts from are Good Sam and KOA. We are Good Sam Life members and I've been a KOA member since 1978. The nature of our traveling and the length of time we travel for, and the "every stop" discount that they offer, though it is only 10%, more than pays for the membership fees that we pay, or used to pay, in the case of Good Sam, and I don't have to worry about restrictions.
My 2 cents, your mileage may vary...
