How about staying for five days and issuing the invoice on the third day?

In the case of staying for five days, the invoice on the third day may be irregular. Usually, the hotel will open the invoice on the day or the next day, because the invoice time and accommodation time need to be the same.

If you have special needs, such as the need to invoice in advance, you can communicate with the hotel to see if you can provide the service of invoicing in advance. However, this may involve some extra formalities or expenses.

In short, when dealing with such problems, you should clearly express your needs and consult the hotel's opinions and regulations to ensure that your requirements can be met.
