Is Passport America worth joining? Absolutely!!! For us... For you, as said, it depends on your RV'ing style. Weekenders will have a problem finding the rare parks without a week end restriction, as will travelers to many popular tourist destinations, particularly during the summer months. During the week and away from the tourist traps, there are plenty of parks to choose from, and saving the membership fee can easily be done in as little as two nights, with everything after that savings that stay right in your pocket.
