We do not pay this ARDA fee, can someone name just one benefit of this organization?????,I also really resent having the ARDA fee listed on my MF bill. ARDA is a lobbying group for timeshare developers. Diamond Resorts adds it to the bill each year and lists it as a "ARDA-ROC Voluntary Contribution". Most people don't notice that it's optional, and don't read the FAQ on the back that says "You may opt not to contribute without reprisal or otherwise affecting your membership.". I call them up each year and ask them to deduct the $7, and keep calling them back until I see that it has been deducted.
