Well, 3rd floor is nice cuz the lobby is also on the 3rd floor. We had a (I "think) Arusha savannah view and it was ALLLLLL the way at the end of the hallway which is a long walk, but then again it was pretty quiet at the end of the hall, so I would actually recommend being far from the lobby, yet still on the same floor. We saw LOTS of animals.
Just asked my DD6 if she remembered our room number...thinking there is NO WAY she would remember, and she just told me it was 3377...and that sounds right.
