The DIS is very good and provides great balanced reviews of the Disney good and bad.
WDW Radio is very good, very professionally produced, and Lou Mongello is a good speaker. I like the podcast, and it has made me a much bigger Disney fan, but it is very positive-biased and tends to ignore the bad stuff.
Mouse Chat is okay, kind of like the DIS, and also a group of Disney travel agents, but not as good as The DIS.
I love My Favorite Murder if you are looking for a non Disney podcast. It’s a true crime comedy podcast. The great thing about podcasts is the diversity of subjects. Explore the search features in the Podcast apps. I just use the Podcast button on my iPhone to listen and subscribe to my favorites. It’s great way to kill and 1 hour while you are doing something else.
I just started listening to the Diz Hiz podcast. It's three guys who discuss one thing about Disney each week, for example they might spend a full podcast talking about the Disney Wonder, or Haunted Mansion. They sometimes stray off-topic and most of the time I know more than they do, but there's enough there to be entertained.
