TPC Jasna Polana was a decent layout, although nothing too spectacular. There were a few fun holes at the end, 16 is a short 4, 17 is a nice over-water par 3 with a wild undulating green, and 18 is a downhill par 5 with an interesting angled green.
However, the best part of TPC JP is the beautiful estate home-turned clubhouse, and the sprawling grounds that include several guest houses where the staff used to live. The great house is very interestingly landscaped, and looks like something out of a movie set.
The only others I've played are the Holly course at Pinewild in Pinehurst, and River Run in the Ocean City, MD area. Both were solid, though not particularly exciting.
