I'm on an unofficial Thousand Trails Facebook group that accepts both the "good and the bad" of TT. At one time there was a period in which there were lots of negative posts about TT. I've seen both good and bad but it seemed to me that there were a lot of people upset with TT. I decided to do a poll in which people could say what their general impression was.
The results were overwhelmingly positive, something like 10 to 1.
Probably the case could be made that those who really had issues with TT have sold their memberships and have moved on, leaving a majority of people who are generally happy.
Still, if nothing else, my findings provide balance to the conversation. In other words, a lot of people who are TT members are happy with their experience.
Having said that, again, it's not for everyone. If you do a lot of workcamping or boondocking or like to stay in upper level campgrounds it's not for you. If you are part time and only think you'll use your membership two weeks a year, it would be a poor investment for you.
We have it, we use it, and we like it. We aren't deliriously happy with it, but our experience is much more positive than it is negative.
