From Manners and Customs of the Bible:

1 Kings 20:16. But Ben-hadad was drinking himself drunk in the pavilions, he and the kings, the thirty and two kings that helped him.
It is not necessary to associate any idea of splendor with these “pavilions.” They were merely booths, (succoth,) as the word is rendered in Genesis 33:17; Job 27:18; Jonah 4:5. In Isaiah 1:8, the same word is translated “lodge”; in Amos 9:11 it is “tabernacle.” Such “pavilions” were nothing but temporary structures of boughs erected to keep off the heat, and even kings were not ashamed to make use of them. It is said that such are still erected for Turkish pashas while on warlike expeditions.
