Personally, I think they were okay.
At first I was concerned because it was obvious that the host, Mike Geohegan, did not have a deep knowledge of the park. However, I realized that this gave him the ability to ask questions that someone "in the know" might not think to ask. I learned some stuff about pin trading (covered in the latest MousePod podcast, too!)
I think the last podcast was the best, since it included the LeAnn Rimes song, a quick interview with Matt, a sneak peek at the online version of the Buzz Lightyear attraction, and a great interview with Tony Baxter, etc.
So, what do other people think?
