Put something in the hotel to make money.

This is actually not a problem, family planning supplies, snacks, drinks, you will know when you have stayed in a hotel ~ many other items are not allowed, you should be clear about it yourself. I have been a hotel for many years. If it is a high-end hotel, I can also set up some high-end consumer goods.

Finally, some guests have high hygiene requirements and can sell some compressed towels, lotions and the like.
