How can star-rated hotels expand their sales channels while observing industry rules?

Judging from the main business of the hotel, at present, it mainly relies on rooms and catering to earn income. The ways to broaden profit channels are as follows

Make a full-field scene for yourself, so that everything in the hotel can be purchased and generate income through product sales.

Instead of letting hotels buy these products, it provides an entrance, and manufacturers can trace back to the entrance of orders generated by hotels.

For example, high-quality ingredients in restaurants, pillows and mattresses in guest rooms, etc.

Through this model, the hotel has become a channel provider, not just an existing identity. As far as cost is concerned, the hotel itself needs those products, so the cost has not increased.
