We haven't done Hoop de doo, but have done Ohana for breakfast twice and dinner once with DS4 and DD1 (last trip 4/08). Our first Ohana breakfast was when DS was 3 and DD was 10 months (4/07). We loved it because the food is absolutely FABULOUS - both breakfast and dinner, and the kids get to do some interactive things too. It seemed like there were different things the kids did at dinner like a coconut race, learning to hula, and other fun stuff I can't exactly remember. At breakfast they get to be in a parade around the restaurant with the characters and they get to hold maracas. The kids had a blast! We will definitely do this every time we go to WDW.
