yeah, you can walk to epcot or studios from boardwalk, yacht and beach, and swan and dolphin. I'd rent them one of those motorized buggies obviously though. perks are early entry to the parks for the most part. disney direct bus service from boardwalk and yacht and beach to the offsite parks. swan and dolphin also has bus service with the caveat that I'd walk over and hop on the yacht and beach or boardwalk bus to magic kingdom because it drops you off at the gate instead of the monorail which saves time. there are some other minor perks like billing to the room for the disney resorts but I don't really do that anyway. there's some other minor crap that I can't remember.
