What do you mean by two bedrooms in a travel agency? Does it include the cost of two people or the round-trip cost of one person?

This is a common phrase in tourism. Double sleeper means that the round-trip traffic is a train sleeper. There is also a saying that a bed is a train. Among them, there are terms like double flight (both by plane) and single flight and single sleeper (one plane and one train sleeper). For example, there is a five-day two-bedroom tour from Shanghai to Hainan, that is, you take the train sleeper from Shanghai to Hainan, and then take the train sleeper from Hainan to Shanghai after playing.
