Translation of drumhead in German

In the coming morning we were picked up to do a day tour in the Mekong Delta. It included several stops all around the river bed and the delta of this huge river. The first station were floating villages.
We arrived at the hotel which we booked in advance but decided not to stay there. Instead the driver convinced us to stay at the Borei Angkor Hotel. We were sure that he would get a sales commission.
We than found out that a plane was leaving 3 hours later to the city of Calama (with the national airline), which was the closest airport to our destination. However, only one seat was available. That was really annoying.
