Of course. We can’t blame the terrain for less walkers here. I know for a fact in most part of the Asia with golf courses built in the mountains , still have close to 100% golfer walking the golf course. A few hole I had encountered with more than 100’ elevation to the next tee box have this amazing flat escalator moving the golfers up the hillside, caddies walked the steep walkway with their power cart. I thought I was in the airport or a department store…
30 pounds for rental is probably not going to work well here, typically in my region, cart fee will be $40 with double occupants, and single rider pays $30. Manual push/pull cart is $15-$18.
Of course the golf course will promote riding carts whenever they could, for one, the extra income, secondly, they believe it’ll speed up the playing pace.
I’d say, for the difficult payout, demand a valid handicap index to allow play. They do this in many parts of the world, so the beginner will stay on the practice range or the executive golf course until they could advance the golf ball to be let onto the regulation golf course.
Again, that is the solution but probably not going to work here neither.
I understand for those golf courses built with development in the first place and golf course second might have the need to ride a golf cart; I just refuse to golf at those courses.
