Free parking at the parks is not a DVC perk, but is for all on-site WDW guests and annual passholders. You can park free at Downtown Disney & most resorts. You can NOT park at Contemporary, Grand Floridian, Shades of Green, Wilderness Lodge or Poly as these are inside the Magic Kingdom parking boundry. If you want to go to a park on your off-site day, pay the fee, you may not park at a resort and leave your car. Non-guest parking is only 3 hours at most resorts (Disney had a huge parking problem with off-site guests).
