How long does it take for long-term guests to check out and re-enter information?

In most cases, if it is only a small hotel, the time to delete the guest's check-in record within one month will generally be more than ten days, and it will be automatically deleted within one month. If you want to find a monitoring system, it will be automatically covered within half a month, mainly because the memory of the hotel's monitoring system is limited and it can't be kept forever, and there are many places that the hotel needs to monitor. Generally speaking, one month is the limit time for small hotels.
