What is the R floor of the hotel?

The name "R floor" is not common in the hotel industry, and it may be the internal name of some specific hotels. Generally speaking, the number of hotel floors is usually identified by numbers or letters, such as 1 floor, 2 floors, 3 floors, etc. , or a layer, b layer, c layer, etc. If you can provide more background information or related background, I can try my best to help you answer it.
