There's no practice facility which Bogey has shared with us, twice. lol!
The practice facility takes place on all four stroke-play courses, and the CTTH is a good way to sharpen your iron skills. WGT offers 10 shots per hole, use these shots to practice iron shots, and various lengths of putts including fringe putts, which you'll need to use more power to execute successfully.
Simply hit back into the fairway, or putt around the greens in practice mode. It isn't the most practical way to practice, but it serves the purpose. : )
