When going to visit the other resorts driving will be a lot faster, although it depends on where you are visiting. For example if you were to visit the Contemporary from there you can take the Resort Monorail to the Polynesian and Grand Floridian. Besides that if your visiting the Boardwalk from there you can walk to the Yacht Club, Beach, Swan & Dolphin. Now since your staying onsite you get free parking at the 4 parks, however the WDW buses will let you off very close to the gate entrances of the parks.
