rufnqaz:
There needs to be a practice green available, since putting is such a large part of the game.
Are you having troubles? I have never understood this suggestion.
The only way to learn IMO is to play the game and to do so by playing the courses we have.
You have many chances to learn putting with a 10 shot max per hole. Equip some starter balls and go nuts. Not sure how rolling a ball on a putting green would serve you better.
