We didn't have a very good experience at Lilo and Stitch. We much prefer Goofy's. We saw more characters and they interacted a lot more with us at Goofy's. I also prefered the food at Goofy's. At Lilo and Stitch it seemed like a free for all with the characters. No one waited at their table for the characters to come around. The guests mobbed each new character that came out. No one tried to stop them either. Maybe that's the way they do it there, but we prefer Goofy's where the characters come to each table.
But I do know that many people love Lilo and Stitch so maybe we just had an off day??
No matter what breakfast we do, we always open the park first then head over to breakfast. You can get so much done in the first few hours after opening.
However, when I just booked Goofy's for a March trip, I was told that the characters start leaving at noon. That was new to me. I've never had that happen before. I wanted to book for 11:30 but ended up booking for 11 since the characters were leaving so early.
