We are already Thousand Trails Platinum members but were somewhat interested in the Elite membership since it includes another bunch of campgrounds in the East which we hope to tour soon. When we found out how much they wanted to upgrade our membership, it just was not worth it. So no they didn't get any more of our money.
Incentive to attend was free camping at either a TT or Encore park and we knew we would be going to one of the Encore parks not included in our present membership this spring so, we took them up on the offer.
