I don't belong to ARRP.I am a Good Sam Life Member but I joined many years ago.Not sure I would do it again today. We rarely use private campgrounds anymore so the discount means nothing to us. We get 50% off Federal Campgrounds with the Senior Pass and state and county parks are generally cheaper than private parks. Plus they are usually more scenic and provide more room between sites.We had a nice large site right on Lewisville Lake near Ft Worth. Regular price was $38 for water and electric. With Senior Pass it was $19. So if you are looking to save money,there is where you should look.
