My last trip was just me and my sister (ages 19 and 23, respectively), and we did a decent job of avoiding any kid issues. Like others have said, eating later is typically better, and it can also be helpful to eat at more "off" times. (For instance, my sister and I usually ate lunch between 1-2pm, which meant the restaurants were less crowded in general than if we had eaten at, say, 11-12. Not only were there fewer wild kids, but we also noticed that we didn't have to wait quite as long for our food.) One thing to keep in mind, however, is the "later is better" idea is a guideline, but not an etched-in-stone rule. Perfect example: we had an 8:50pm reservation at Coral Reef, so we didn't expect to have to deal with kids. Wrong! The table right next to us had two kids (both under the age of 8) who would not stop whining, refused to eat, and kept trying to get up and run around. Of course, I understand that it's Disney and there will be kids, but that was ridiculous! Basically where I'm going with this is do what you can to avoid kids as much as possible (eat late and at off times, don't do character dining, etc.), but unless you eat at Victoria and Albert's, don't be surprised if kids do make an appearance.
