No fee for a transfer -- other than the cost of renting the points from the other member, which will be a private transaction between the two of you that won't involve Member Services. Your challenge is going to be finding someone willing to give up their one transfer to send you only 4 points. Considering that the going rate for rented points is $10 - $12 per point, I'd say the frustration factor of finding someone to rent from and then coordinating the transfer and payment would be worth paying the extra $20 it would cost you to buy the One Time Use Vacation Points directly from Member Services.
