when thousand trails and outdoor world resorts were separate companies People would own both memberships. $500 membership got you 2 weeks in system with 1 week out of the system.
So you would have friends who are in outdoor world site for 2 weeks while your in TTN site.
When its time to switch you send the wives ahead in the toads to hold site. When your friends wife shows up, you pull out in you RV and head to other campground and she pulls into site to hold it until XO shows up with the RV.
You can full time your whole Winter in Florida for the price of 2 memberships. If you have enough of you doing this you could have other switching every other week and you could spend 1/2 the time with all your friends. Each membership ran $500 year so if you stay in FLA for 9 months it comes to $3.75 per day including electric.
Than there was the couples that were not married, and each had Thousand trail memberships. you could use your membership in a campground for 2 weeks, than the XO could use here membership for 2 weeks, than back and forth, without even moving.
