Yes, generally, one spectator is allowed with you to the golf course. However, this depends solely on the policy of individual golf courses. Some private golf courses do not allow anyone other than members. On the other hand, some give permission for family or one spectator along with the golfer. If you want your spectator to ride along with you in the golf car, you need to know its availability. The person will have to pay an additional fee for riding along with you. In case of carts are not available, then you might need to walk. The priority will be given to booked golfers and then to the assisting spectators.
