Which type of window is typically not suitable for use on a hotel balcony?

Hopper windows are designed to open inward and are typically used in situations where space is limited, such as in basements or small bathrooms. Their design is not ideal for hotel balconies due to safety concerns and functionality. Because they open inward, they can obstruct the balcony space and create hazards, especially in high-traffic areas like hotel balconies where guests may be moving in and out frequently. Additionally, if a hopper window were to be opened while someone was standing immediately outside on the balcony, it could create a risk of accidental injury.

In contrast, double-hung, sliding, and casement windows all have designs that allow them to function more safely and effectively in a balcony environment, either fully opening outward or providing better ventilation without interfering with the space.
