AKL has bead activities for the kids. For each activity complete, they receive a bead for their "necklace." If all the activities are complete, they receive the totem bead. It's pretty cool. When we were there the schedule was: flamingo feeding (9:00), animal tracking (11:00), Junior researcher, (1:00 or 2:00), music of the savanna (5:00), and animal games (6:30). All the times are posted by the bell services desk.
They also have cookie decorating (we couldn't squeeze this into our schedule) and medallion rubbings (which someone has already mentioned.) There are pool activites as well (i.e. family pool games, games with the lifeguards, arts & crafts with the lifeguards.)
We did the Hidden Mickey search too - it was great fun! There were about 15 or 20 throughout the resort. The kids loved the gift shop, too.
We loved AKL. We added an extra day to our last vacation just so we could hang out there. We made a day of activities at the hotel and still didn't get finished.
