Some of the happiest Thousand Trails members I see at almost every campground are working families. They buy a zone pass and pay near $4,000 per year to have a year round personal site (+ electricity).
They leave the rig on the site most of the year. Most good weather weekends they are at the campground. Mom brings the kids out after school. Dad might bring the boat, or come straight from work. They don’t leave the CG until dark on Sunday. They know they have their spot for busy holiday weekends. They can hitch up the trailer/5er and hit the road any time they want and know their spot will be ready for them when they get back.
I see more young couples with this type seasonal spots than I see in COE campgrounds or state parks. Not only at Thousand Trails parks. Many commercial parks across the country have the same type of seasonal sites.
It is something that has never appealed to me. But my father would have done so if such a park/site was available on the lake he loved.
Again as said above - if you will use it, if you can meet your goals, a membership program or seasonal program can be wonderful.
But it is essential that the purchaser knows what they want.
I don’t think we would have been happy with Thousand Trails if we had not spent two years full-timing and traveling to over 20 states/ 15,000 miles before buying into TT.
From the original post I don’t think TT is a good fit for the OP, but I still really don’t have a good idea what the OP is looking for.
