As said, it depends on your style of RV'ing. As very long termers, we have Passport America, Escapees, Good Sam, and KOA memberships, and all of them more than pay for themselves each year. With our Escapees membership, for instance, we stayed for five weeks in a club owned park in central FL from late January to early March for an average daily rate of $14.50 for a full hookup site that was spacious, shaded, and next to a small pond. Last week we spent four days at a nice KOA in southern GA just over the FL line at no cost, just using our accumulated points from other KOA stays. Check the requirements and and discounts for each card membership, and if it appears to fit your RV'ing style, go for it. If it doesn't work after a year, drop it.
