It would be great if WGT could organize with Trugolf to allow only one day each month where WGT players could be exempt from having to pay the green fee.
They would surely gain revenue following this promotion of Cabo and Whistler than losing revenue by waivering fees for just a single day.
For just 1 day out of 30/31 it would give many more players a taste for the course which would result in increased profit for all those players who trialled the course for free, enjoyed it and proceed to play on any of the other days of the month paying the green fee.
I'm sure that someone will come on here saying that it doesn't make business sense and that every credit in green fees is vitally important to the sustainability of the business but business is also about marketing and generating interest.
As for frequency that's up to WGT and Trugolf but I remember playing Cabo for free one time so it could happen.
