Not sure if this has been already put forward but here we go anyway.
I've seen people suggest a need for a driving range and putting green and yes both would be a great addition but for me a clubhouse would be the most advantagous.
You might think what good is a clubhouse but for me one of the features lacking is a chat room where players can meet and agree to join friends for a game. I know some country clubs do they're own but i think this would make a good addition to the WGT experiance.
At the moment you have to invite a player to a game to get to a chat box to decide and agree on what you want to play.
Anyway just a thought, anyone agree?
