Okay, so Prossy is a legend. By far the best customer service I have experienced in East Africa.
As a solo traveller, I was joining a group that day. Turns out there was a last minute cancellation, and there was only 2 of us going. No matter, the trip still went, with all the bells and whistles.
The trip itself was really wonderful. The guide and team were friendly, professional and fun. The Nile is beautiful, lots of birds, we even saw a snake swimming and some otters. And the rapids were huge fun.
Being vegetarian was no problem at all, and the food was really good.
