When I asked a member of staff if there was a Crazy Golf course on Constitution Hill she said that there wasn't but lots of people had been asking about it. I wonder why!
There was however a 9-hole Frisbee Golf course. I played five of the holes and then gave myself sevens for the final four holes as it wasn't anywhere near as fun as Mini Golf and Crazy Golf.
As a sort of very poor consolation 'prize' I did manage to find an out of order 18-hole Putting Challenge Minigolf Arcade Machine in the 'Games Room'.
