I too have a membership in Thousand Trails, and before upgrading to the Platinum Membership (no time outs and 3 weeks in each preserve and one can go directly to another preserve), I had a 14 day max then 7 days out of the system - annual dues were $500, purchase price (resale) was $1,020 which included the $750 transfer fee. Then too there's the affiliate program RPI, or the 50% discount camping membership of Enjoy America.
Although I have done major budget cuts at home (upped deductibles, unbundled package services on phone, etc., and returned to dial up for the computer), the 'savings' haven't all kicked in yet, so my last trip, I was able to utilize Passport America's discount and was pretty pleased with the results....no restrictions for Art's RV Sites in Fayetteville, NC, so enjoyed my stay for $12.50/night and was able to accomplish the delivery of my daughter's washing machine to her new home, spend quality time with her and husband as well as rest/relax and indulge in a passle of reading!
It just killed me to spend double on the trip cost (gas) that I did just a year or so ago. And, I'm becomming obsessed with entering the costs in my journals now. But, I sure was pleased with the Art's RV Sites and the Passport America rate. My 5 night stay paid for the annual membership and then some!
