We didn't stay there, but we arranged a trip through the Nairobi Hilton to visit the Giraffe Park, not the hotel. We were on a raised platform and the guide gave us giraffe kibble to feed to the giraffes. He even showed us to put a pellet in the mouth, so the giraffes could kiss us. From what the guide said, giraffe tongues are antiseptic. Who knows? But I didn't get sick from it. This, by the way, was on the same trip where we met you, SanDiego1K, the famous Hilton Award at Salt Lick Lodge.
