Not bad considering the quality of these tours and what is on offer. They rarely discount these tours which makes it more enticing.

I did one of these years ago. Had a good trip, but very uncomfortable as they used mini-buses with tiny little seats.
Very unpleasant to cross the continent in one of those, compared to a normal bus (e.g. Contiki), and I'm not even tall.
Have they got better buses now?
Green Tortoise was the best, as seats converted to beds at night.
Also, the drivers got paid very little, and mostly did it for the considerable fringe benefits.
