① The production and existence of the use value of hotel products must depend on a fixed space, and these use values have a strong time utility. ② Space is the shell of hotel products and an integral part of its use value. Hotel space is immobile, which determines the immovability of hotel products. Although the hotel space cannot be moved, the function of the hotel space can be changed temporarily or permanently. For example, change the function of the multi-function hall or temporarily change the karaoke room into a small dining room box. ③ Time is the carrier of hotel products, and the use value of hotel products is closely related to time. Formally speaking, the value and use value of unused hotel products still exist, but this existence exists in a new period. The product value and use value of the previous period are idle because they are not used, which is a loss. Therefore, the value of hotel products has a strong timeliness. ④ Observing the time and space of hotel products together, we can find that space and time are interrelated and intertwined, which has an impact on hotel products. In order to make every space in each period produce ideal benefits as much as possible, the key is to improve the management level. ⑤ In order to realize the product value, the hotel can't leave the space idle, so it needs to attract customers through marketing and make full use of the hotel space. And the use of this space is related to the time period. For example, in the off-peak season, hotels use price leverage to adjust passenger flow, which is to use the space-time characteristics of hotel management.
