I have never been to Disney World with kids (except when I was one!!), and I don't really do anything specifically because I don't have kids with me.
I eat where I want to eat whether it's child-friendly or not. Heck, one trip I even went to two-character breakfasts in one day because a cast member told me that the "John Smith" at the Pocahontas-themed character breakfast they used to have at Artists Point in Wilderness Lodge was quite attractive *and* then another breakfast at CRT because at the time, that was the only place to see Prince Charming (same cast member told me Prince Charming was a major hottie). My friend and I got the added bonus of seeing Snow White's prince as well who was cute, although definitely not as cute as Prince Charming was. This was when the breakfast at CRT consisted of several princesses and their princes (Cinderella and Prince Charming, Snow White and her prince, Jasmine and Aladdin, etc).
I would definitely recommend some of the backstage tours though, because for those you have to be above a certain age to even be allowed to go.
