We used Campclub on our four month trip around the country two years ago and found it worth the money. As stated, your payback comes quickly. We would look in the book for camping near our destination and if it worked for us, we would stay. We ended up in some real nice places. The book describes the rules for each camping experience with regards to the discounts and amenities. Our most recent book has to be three or more times the size of the book from two years ago. They have added a lot of places.
We never bought Passport, so cannot comment.
