As I've said in a previous post somewhere here lol Kidani is our 'Home' resort. We always stay on Sunset Savannah for just that reason (I'm a giraffe lover
), and I know that Sunset Savannah is shared with Jambo, so maybe request that one. Someone here that usually stays in Jambo might be able to help you further with that if there is any other savannah the giraffes are found on over there. Also, the giraffes are very often viewable from the lookout points off the lobbies of both resorts (we even saw them sleeping at night on our last trip in Jan).
The animal specialists make sure to widely distribute the animals food esp the giraffes to encourage them to move around the savannah.
Have a great trip! Your DD is going to LOVE IT!
