We love Ohana breakfast and it is our family's departure day tradition. The character experience is very good there and Stitch has always been outgoing and playful.
I generally like the food, but its not for everyone (I'm referring to the ham, I'm the only one in my family that eats it). When we went there a few weeks ago the eggs and potatoes were both insanely salty. Not to the point where we didnt enjoy them but it was very noticeable. I don't know if that is common lately (our last time prior to this was 3 years ago).
IMO you will have a good experience at Ohana if you have proper expectations. Places get overhyped and that's when people get let down. Topolino's character breakfast is better overall, but we love Ohana also.
