I've booked and paid for this already with Churchill Safaris. They have a good reputation, but aren't the cheapest lot out there. I wanted the confidence that I wasn't going to get ripped off and that I'd get a reasonable quality trip, so the extra couple of hundred dollars I'm paying is worth it IMO. As it's already booked, the trip dates are inflexible, but if anybody else is in the area at the same time and is looking for a way to split costs, let me know!
