I made this suggestion to WGT at the time of Cabo's release, it fell on deaf ears then as it will probably do now.
How about selling a pass in the WGT pro shop that entitles the pass holder free unlimited use to the TruGolf courses (as long as the fee is not set too high).
I'm sure these passes would be bought if priced correctly and even gifted to others from some of the more benevolent members.
Let's face it, as WGT proved by lowering the initial prices, the take up on green fees must be far lower than was initially expected, but a one time fee would be a way for the hardcore members to upgrade their WGT experience should they so desire.
For arguments sake, set the fee for a pass at 10x the normal green fee for a full round. I'm sure TruGolf would be impressed with the immediate rush of credits into their bank account.
Obviously, for the RG rounds, the fee would still be paid, but if an Alt shot match could be set up when all 4 participants had passes, many in the WGT community would snap up a pass.
I appreciate this may not be the best solution for the players, but it is a sensible compromise for us members, WGT and TruGolf.
