Translation of negotiator in Spanish

The airport was huge, compared to Siem Reap's one, of course. We expected something similar to Bangkok's airfield but it was completely different. We stood in line for the passport control.
And off we went. It took a us only a few minutes to reach the village. Funnily my wife fell asleep as she was still tired of the flight. It has been more than twenty eight hours without sleep.
The next morning she felt much better and we decided to take the bus to Puerto Varas, a small town near the Osorno volcano. The bus ride took around 13 hours and we passed through various, but not very interesting landscapes.
