There's a thread about closed resorts and it was recently reported that another Festiva resort, Church Street Inn in Charleston, SC has bought out owners and is closing as a TS. Have no idea what's happening with CGM other than the year old story they were operating without a valid business license. Very odd that there wasn't prior communication with owners or exchange companies.
As for closed Branson TS, there was also Roark Creek. And HICV's Ozark Mountain in Kimberling City.
