That's pretty much it, although, sometimes, certain panelists are chosen to go to certain media events and oftentimes, they do stuff for media in their own hometowns. I did a huge interview for a big Savannah magazine and it was pretty cool. Sometimes you're asked to participate in the filming of videos that Disney will use for various projects too. If you like that sort of thing, it's pretty awesome!
Also, and I may write more about this at some point, but when the 'Moms' answer questions on the panel, they do it based on their own experiences as guests at the parks. So, it's kind of a YMMV because not everyone's experiences are the same and interpretations can be so different - it's all very subjective. I remember back in the beginning of the panel, there were always accusations flying online about people thinking the Moms Panel people didn't know what they were talking about, but when you know their answers are based on their own experiences, you can understand that everyone experiences the magic differently.
