Yes, the swimming and pool games, and gameroom. You are correct, no water activities like boats. My kids also enjoyed going all over the hotel pin trading with the CMs, there seemed to be a large number of CMs with pins to trade with. The also have many of the activities hosted by students from countries in Africa. They are very interesting and always willing to talk to you about where they are from.
~ Build an African Bead Necklace by participating in Flamingo Feedings, Animal Tracking, Junior Researcher, Music of the Savanna, and Games with Savanna Guides.
~ Also have: Horticulture activity, Culinary Tour of Africa, Cookie Decorating, Spirit of Africa Art Tour (art exhibited all over hotel), African Folktales around the Firepit, Animal Viewsing with Night Vision (if you have night vision on your video camera it works too), African Safari with Medallion Crayon rubbings, Pool Activities, African Games and Crafts.
The gift shop is great and has all kinds of African items to look at and on one of our stays had teens from Africa actually making beautiful natural art. The restaurants are awesome and BOMA especially would be a good thing to PS on a hotel day. There are lots of different spaces to view animals from, some with chairs & lenses. The art and artifacts are also spread all over hotel, so it is fun just to explore.
