Yes, very much. We had the character breakfast at O'Hana. I think we just had a bad experience with the server we were assigned to. She took forever between table visits. We didn't get drinks for about 20 minutes. We asked for extra waffles when she brought the initial serving of food. Only 4 small Mickey waffles came with that serving. I had to ask her twice more before she finally brought them. The food was decent, about what we expected for family style servings. On the plus side though, the character interaction was really good. Stitch was very playful with our DD6 and DD7. He played with their pony tails, tossed sugar packets in their laps, and just generally was mischieviously hilarious. The food filled our bellies and we had fun with the characters, but the poor service kind of jaded our opinion of O'Hana. I wish we would have been able to try O'Hana for dinner for comparison.
We also had breakfast at the Kona Cafe. Our server was great. As we were first-timers there, he spent some time explaining the menu. Delivery of food and beverages was prompt, and the food was much better than O'Hana. I had the Tonga Toast and would highly recommend it. There's also something a little bit more satifying about ordering individual choices from the menu as compared with a one-size-fits-all meal at the family style places.
