When we got our Thousand Trails membership, we also got a membership in Resorts of Distinction. We pay yearly membership fees for these (roughly $500 for TT and $200 for Resorts of Distinction) then we can stay at any of their parks for free. So - we found an ROD park on our way - in Benson Arizona. Nothing special, but it sure is nice not to have to pay. I have to keep reminding myself that it's *not* free ... it is prepaid. The more you use it, the cheaper it gets.
