Holiday Inn Club Vacations includes the voluntary ARDA contribution in the "Amount Due", you must maually change the "amount due" to avoid making the "Donation". Furthermore, the amount of the donation varies between $3 and $7 on each Contract with no logical reasoning for the differences. However, the Bill Payment system only displays the Total Amount Due, INCLUDING the ARDA donation, it does NOT display the amount of the ARDA donation. So, when paying the maintenance fee bill on-line, so you must refer to back your Bill to determine the correct amount to deduct. Clearly, their intention is to make avoiding the "voluntary contribution" as difficult as possible!
