question about interval international ?

hi

Interval international does not respond to non members so i need somone that can tell me and provide me with the following info Which clubs are affiliated with II? Can someone send me a points user guide? What is the exchange fees locally and internationally and how does it work? How can one avoid the exchange fees as i am aware that some weeks deposited with RCI that are RTU there is no exchange fees and it only deducts rci points from the points user guide and members get 35% discount if booking in instant time.
