We did it in October. Lilo wasn't there (we figured Lani grounded her), but Minnie was there in her place. For us, the Ohana breakfast is our tradition (I've been a regular since it was Minnie's breakfast).
For us, the nice thing about this breakfast is that its served family style. No juggling of buffet plates with kids (though now they are getting old enough that it isn't a bother). Other people don't like that, however, since a buffet selection is broader and you control how much food you get and when. With a table service character meal, your server can make a huge difference!
We had a bad experience here a few years ago with a late seating - by the time we were seated - 40 minutes after our PS time, the characters were going off shift and swung by the table before our food even arrived, then left the restaurant. But that has been the exception.
The food isn't great (I haven't had character meal food that is), but we enjoy spending time seeing the Poly, character interaction has been generally good, and its easy to make an early breakfast and still walk into the MK at opening.
