Yeah, China was my big worry, I'm still debating over it.
Basically I have a chunk of my trip sorted, bog standard route - Fiji - New Zealand - Australia - Malaysia - Borneo - Thailand - Cambodia - Laos - Vietnam... Then I'm not sure whether to start in the US and then do them, then finish in China, or start in South Africa and finish in Vietnam and miss out China, or do South America (although I have been warned off here as a female)... I don't know, I'm a bit confused.
Anyway, back to the original topic... what are other companies like then aside from Real Gap, such as Intrepid?
