I thought that it was a really fun place for the kids. Our kids were 8.5, 5.5, and 3.5, and the two younger ones loved it, and loved dancing with JoJo and Goliath. My 8 year old thought that he was too old for that, but did enjoy just watching. Another fun breakfast is TH at Animal Kingdom. Lots of fun dancing there also.
I would really try to get to this one early. We had 8:35 am ADR's, and actually got there about 8:00 (very quick bus service!), and were seated quickly. We were out into the park by 9:15 am. While we were eating, it was not crowded, and was not loud. Characters came out by 8:30, which was good since my kids were able to eat and actually finish a meal before they lost interest due to all of the activity (characters).
If you are like us, I planned alot of character meals, and the kids enjoyed seeing them up close, and never bugged us about waiting in line to see the characters. I think they actually preferred knowing that they would be able to get the one on one time without wasting time that could be spent doing all of the attractions.
