Im confused here, you are or are not a member? If you are- You can call and check on availabilty yourself! you dont need someone else to call for you!
you are within the 7 month at all those resorts-then if its available do a transfer of points DONT rent them. Its the same thing, costs the same, but you OWN the points
renting is typically for non-memeber and tranferring is for members-unless you are renting for a pre-booked time frame that no longer is available.
