I have been a member for the past 8 years. Yes, I definitely say it is worth it. You should be aware the most of the campgrounds that participate in Passport America are the one and two star category. Don't expect KOA type grounds. There are some higher quality but that is not the typical. But if you are looking for one-night stays for traveling this works great.
