Friday RCI released its new policy which will allows Johnson to make changes without a fee: "Group RCI will provide its members inbound to Mexico for RCI exchange travel within the next 14 days the full exchange value of their week back and fully credit their transaction fee for an exchange reconfirmed within the next six months."

"It was unprofessional, slow. They weren't looking out for my best interest, that's for sure," said Scott.
ABC7's attempts to reach Apple Vacations for comment were unsuccessful.
