There are many great Disney World-related podcasts out there. All have very different formats and angles by which they bring you their show, and how they present their content.
I love the Dis Unplugged because of their well-rounded and diverse views...positive, negative...it's honest all the way. And it's helped by the fact that the whole gang are never afraid to voice their opinion about anything. Very entertaining (and informative - the news segments are great - and it's not just a rattling off of news, you get their opinions real-time on the news as they read it off).
I love Lou's WDW Radio Show BECAUSE it's so positive - it's a celebration of Walt Disney World...an he makes not apologies for it. I think that's a great thing. If I want to be in a good mood, I turn on Lou's show. And it's also extremely informative. Lou's knowledge of The World is second to none.
I love WDW Today because it's short, and 3 times a week (sometimes more if they have live broadcasts). They too are funny, entertaining, and above all, very informative as well. Len Testa (co-author of the Unofficial Guide) is a huge asset to the show as a regular co-host.
I also love Inside the Magic with Ricky Brigante. His is more straight forward information and he provides a lot of binaural audio of parks, songs, shows, etc. Very interesting.
Those are my 4 favorites, and there are other good ones as well. It's nice to have a variety of so many quality disney podcasts, each with their own unique flavor. So listen to what you like.
