Mr. Disney Magic discovered this first, with a free episode on the history of Adventureland (I think it was) on Amazon Prime. When I found the podcast, I was over the moon! Lou Mongello seems to know everything about Disney. The history, the behind the scenes, everything. What make's part of that so interesting, is that he had been a lawyer, closed his practice and moved to Florida to do what he loved best, Disney. He also raises money to send kids to Disney, through the Make a Wish Foundation, and I have to say it, honestly has one of the best voices for radio I've ever heard.
Dis Unplugged is another great place, and what I like about their podcasts I only discovered recently. In addition to their regular podcasts on the topics I mentioned above, they also have an addition different podcast that's a spin off just on the historical side! They also have a specific podcast genre for Universal, Disneyland, Disney World, popular Disney culture, and more. Each is it's own separate podcast, so for example, those just wanting Disney World info of history, aren't going to be listening to the top 10 places for lunch at Disneyland. There's a pretty big team of people doing the podcasts, so you don't always get the same group each time. They have so many podcasts, there is bound to be something (or a dozen somethings) that matches your interest!
I haven’t listened to as many of these podcasts, so I don't have as much to say, but they also have been good general information sources, as well as a lot of listener question episodes, so you never know what you will get with those, they might be questions you have as well, or ones you'd have never thought to ask.
This is another one I haven't listen to much, there aren't as many podcasts on here, and it seems to have a lot of trip reports, sprinkled in with some other info, but sometimes trip reports are really useful for when planning your own trip, especially a first trip, that's why I included it.
I am sure there are tons more Disney podcasts out there, these are just my favorites of the ones I've run across. Do you have any you could suggest to me?
