We found that the C&CC struggled to sort out an itinerary for our independent tailor-made trip. I think they are probably very good at scheduled trips/visits but we wanted flights, stopovers, other countries included (they advertise as something that they can do). We found Trailfinders really on the ball so booked most things with them - including campervan hire in OZ at a price we couldn't find cheaper.
We had help from C&CC for our six week independent trip for NZ and Hong Kong last January and all the arrangements went without a hitch. Not cheap but at the time we hadn't had much time to research and book it all ourselves.
Have you done your trip yet Richard? Hope you enjoyed it as much as we did. Would love to go back but extremely unlikely.
Fond memories of Trailfinders - in 1977 three of us paid £60 each for overland local bus vouchers from Turkey to Delhi. Goodness knows how the system worked, most of the places were in the back of beyond!
