I researched scads of safari companies, and we finally decided on a 3 day tour of the masai mara. We’re a little pressed for time in our travels, and the safaris are actually so much more expensive than I had expected! But I think 3 days will be sufficient, and we are also going to the Giraffe Center and Elephant/Rhino Nursery on the 4th day. I just sent the confirmation email to book the trip, and we already purchased our tickets to Nairobi last week, too. Nothing left to do but count down the days :)
