There is a little Nemo ride, turtle talk with crush which is kind of like a show but it interacts with the kids, huge "acquariums," boat ride through greenhouses, imagination ride with figment, 3D show, energy/dinosaur show/ride, play and learning areas, cute boat ride in Mexico, boat ride in Norway about trolls which can be scary for little ones depending on the child, kidcot stations where the kids can do some coloring in each country. If your kids are daring, there are a couple rides you might want to try -- Soarin' and Test Track for 40" tall. Mission Space is for 44" tall.
If you want to do a fun meal for the kids, Coral Reef is a fun restaurant with a huge acquarium wall of fish, sharks, turtle, etc., for the kids to view while you eat. There is also a character meal at Garden Grill (we were thrilled with the food, but many people love it). Don't recall if your kids are girls or boys, but there is also a princess character meal in Norway. Japan is fun (and good food) where they cook right at your table.
