with campground memberships a few factors should get careful consideration
1. location .... if the CG/CG's are where you want to go a membership should be considered .... if not, no matter how good a deal it may be, a membership would be worthless
2. economics .... its always nice to make a profit on something like this but it isn't mandatory .... the decision boils down to if the cost involved is worth it to you
3. preferences .... do the CG/CG's offer the amenities that are important to you .... if so, that would be positive .... if not, a major negative
the recommendation to, when possible, buy a "used" membership is a good one .... we purchased a used Thousand Trails membership back in '02 .... some years we saved money, some years we broke even, some years we lost money .... during that time the enjoyment we got from camping at their parks was worth the cost .... now that we have retired and have more time, the economics have tilted heavily in our favor
