I am practically the Queen of Values. (well... princess, I guess
) My family never stays anywhere else, with a few rare exceptions, because of the money issue. No, they're not as fancy as moderates of course, but they still have all the Disney touches - nice decorations, clean rooms, friendly & helpful CM's, etc. We love them. As far as suggestions, here's a map from wdwinfo.com that shows where the buildings are.

ASMusic is at the bottom in blue. Calypso 1 & 10 are the closest buildings to the lobby, but I think they're preferred locations so you might get charged extra for them. Not sure though... Hope some of this helped and I hope you have a great time! :)
