Why do frequent fliers plan to upgrade hotels with lower accommodation requirements and higher accommodation requirements?

For example, many hotels, especially city hotels, have a large number of long-term guests, some of whom have stayed for several years at a time. This kind of guests get very favorable bargaining, and basically only live in this store of the group. So, if you are the policy maker of the group frequent visitor program, considering this situation, would you encourage staying more or staying more? One more thing, 1 night is at least 1 night, or it may be 2 nights /3 nights /4 nights ... and 1 night is 1 night. Based on the principle of maximizing income, of course, stay earns more. In addition, some people may say that if I stay at 10 for one night and stay once a day, will it become 10? Actually, it's better to buy than to sell. The definition of valid check-in in the frequent flyer program is that the interval between two check-ins is at least 1 day, and the hotel is forbidden to stay multiple times. As for whether it will be unfair to stay in the membership, first of all, the hotel will inform the members of the benefits of the program when they join the club, and the members will complete it with the voluntary consent of both parties. Secondly, the same is true of other frequent visitor programs, which are already industry practices and are not comparable. In addition, for basic members, 1 year may only stay a few times. Accommodation and overnight stay are basically not sensitive issues, or most people don't really care. For many senior members, a person who can complete 25 stays or 75 nights a year will care that I stayed for two nights. Why don't you count two stops for me? Accommodation and night are not a problem. They are often members of several frequent visitor programs, and staying in a hotel is more like completing the tasks of each family in a sense.
