Translation of fume in Spanish

We drove to the airport to do early check-in but it went so quickly that we had four hours left before our flight departed. We therefore took a cab back into town and visited the local market.
A flew hours later we landed in Siem Reap. The land around us was amazingly green and the weather was very humid. We were still in shock while driving into the city center with our driver.
We checked in at the Hotel de Paris, a small hotel owned by a friendly, old lady. Our rooms were OK, but we asked to be transferred to the newer part of the hotel. The stomach ache of my wife did not disappear.
