Great choice! I would have recommended Jambo, also, especially with an 11-year-old. The pool at Jambo is wonderful. The pool at Kidani is quite nice, but not as large as the pool at Jambo. There are more activities at Jambo, I believe. The lobby at Jambo is more impressive, and the store is larger. In my opinion, the main situation where it is an advantage to be at Kidani is one we have often had: six guests in a two bedroom suite. You get three bathrooms at Kidani vs. just two bathrooms at Jambo. Sanaa, the restaurant at Kidani is worth visiting. The bread service is outstanding and the meal choices are really good. It is not as expensive as Jiko. Also, they have a quick service breakfast, where you can sit at a table and look at animals just outside--maybe more interesting for people of our age than for the 11-year-old, but still quite nice for one morning.
