Design a vending machine for a hotel lobby.

Focus on the unique needs of hotel guests when designing the vending machine. Consider the types of products that would be most appealing, such as snacks, beverages, and travel essentials. Think about the user experience: how will guests interact with the machine, and what features can enhance convenience, like touchless payment options or a user-friendly interface? Additionally, consider the placement of the machine within the lobby and how it can be visually appealing to fit the hotel’s aesthetic. Finally, address any potential operational challenges, such as restocking and maintenance.
