Hotel 16 is 1. Is room 16 full, room 17 empty or room 16 empty?

The so-called 16 free 1 8 free half fee refers to the hotel's service policy for the tourism team. In the past, travel agencies were often required to pay the room rate of full-time tour guides, so hotels provided travel agencies with the policy of 16 free 1 8 free of half fee, which is the embodiment of humanized service considering that travel agencies have to bear the expenses of full-time tour guides, rather than any preferential policy, and of course it has become a tourism industry.

/kloc-rooms above 0/6 1 free, 17 free. If the room exceeds 16, minus 1, which is called 15, the hotel charges 16, and 17 is free. The 8th is also free, and Room 9 is half price for Room 8. The same reason as KFC's second cup is half price.
