Im not to sure if you can actually drive to the resorts and park. Last trip we went to my parents had to have a pass to let them into the gate. There is always someone on guard at all the resorts. If you are staying at a WDW resort than i would recommend a bus. For getting to beaches and cream you could take the bus to either MGM or Epcot and them walk or take the boat from these parks to the Beach Club. Just remember to get back to the bus stop before the park closes. As far as the Boardwalk goes you might want to ask the conceirge when you get to your hotel. I know that there no parking at the beach club but there might be at the boardwalk.
