You should be able to search for all of them on the wdw site. You might have a delimiter of Epcot Area Resorts.
Beach Club
Yacht Club
Boardwalk
Swan
Dolphin
Those are all easy walking distance. No more than 10 minutes walk from the IG. Swan/Dolphin will not accept Dining Plan credits, but if you're paying OOP, you might want to give their restaurants a close look. They are said to be VERY good. I happen to think Kimonos for sushi is an absolute gem.
