Hey Jonny. It’s not cheap but not crazy. Airfare should be under US$1000 from the U.S. (It was that from MN a few weeks ago, and oil is still low.) A matatu to the Mara is probably US$50 or less. And if you can rough it a little, Jackson and his crew will answer your email at the site for the link I put in the article. They are not Disney; they are real-deal Maasai. Their English is good, and you will find they have a way of saying things much more eloquently in English than we ever would.
