What is a common desire for non-passenger terminal facilities?

A common desire for non-passenger terminal facilities is the inclusion of a cell phone parking lot. This facility serves an essential function in modern airport operations by providing an area where awaiting drivers can safely park their vehicles while they pick up arriving passengers. The demand for cell phone parking lots has grown in response to evolving transportation dynamics, particularly with the increase in ridesharing services and the need to reduce congestion in front of terminals. Such designated areas help manage traffic flow, enhance safety, and improve the overall experience for both passengers and drivers, making it a sought-after feature for airport planners and operators.

The other options, while relevant to certain aspects of the airport experience, actually pertain more to the terminal buildings rather than non-passenger terminal facilities. Therefore, they don't align with the specific focus of the question.
