I would love to go but I don't know if pre-booking a "expert guide" is the best way to see the park.
Should I just go to Arusha and then figure things out there?
I've been told you can get relatively cheap flights from Arusha Airport into Lake Manyara - they fly out twice daily and take about 25mins, I've seen fares for around USD$75-90. Check out - http://www.coastal.cc - as one option. I had a look to see if there were any car rentals, apparently most can be organised locally or through hotels in Arusha.
