1. Have 1 course per day designated as the golf cart course - Wednesday through Saturday - on a rotating basis. Walking all 4 four courses Sunday through Tuesday. That way, an older person could play all 4 courses over 4 days. Plus, it would not hurt the vibe because the walkers would avoid that 1 course each day that had carts - ie. if I went there, I would play 36 at Pac Dunes and Old Macdonald if Bandon Dunes was the cart course that day. Plus, 1 day of carts per week would not be detrimental to the courses. Plus, they can get rid of the doctors notes.
2. Have "bag carriers" that cost $40-$60 per round instead of the $80-$100. That would allow them to keep only the best caddies and get rid of those with attitudes (which I saw a lot). Plus, it would lower the cost for the average guy.
