A pp made a good point about how do they find these tiny bus station booking offices in big cities. With no maps it seems an impossible task. They can ask people but there must be loads of these offices. How do they find the right one? Also how do they find the off the beaten track farms?

There won't be many buses to get to their out of town remote "work" places, so do they pay to get a taxi to these places - or is it not part of the budget, just so the producers can get some good TV in?
For India - Official booking offices will be in or near bus and railway stations. Loads of tiny "travel agent" type places will also sell tickets (at least in the relatively touristy places they pass through). So it's more a case of finding any one, than finding a specific one. If one doesn't sell tickets for a particular route, they'll point you in the direction of someone who does - with moto rickshaws (tuk tuks) or motorbike taxis to take you there. It's cheaper to buy direct from the official place, of course - but I found a few extra rupees could obtain tickets when the official office was closed, crazy queues, or "sold out" (this was 10+ years ago, mind!)
In terms of getting to out of the way work places - if it's set up for tourists to work there, there will be a way. Bus to the nearest village - I don't think it's as bad as the UK for more remote places having little/no public transport. (Maybe buses that only leave when full rather than a timetable...). Then someone from the work place picks them up or motorbike taxi/rickshaw/taxi to the location (which locals will know as they will see a stream of tourists going there).
I wish they would show more of this, though. And of places they stay, and considering budget. In agreement with all the comments about backstories being too long!
