What is one key difference between physical and virtual events?

One key difference between physical and virtual events is that virtual events eliminate the need for physical space and travel. This distinction is significant because virtual events can be attended from anywhere with an internet connection, enabling broader participation without the logistical challenges and costs associated with traveling to a specific location. In contrast, physical events require a venue, which involves securing physical space and often means attendee travel expenses, making them less accessible for some participants.

The other options do not accurately reflect the core differences. For instance, while physical events often involve detailed contracts due to the complexities of venue arrangements, this characteristic does not universally define them compared to virtual events. Moreover, physical events do not allow for unlimited attendance since venue capacity typically limits the number of participants. Lastly, virtual events are generally seen as more cost-effective, meaning that they often require fewer resources to host compared to their physical counterparts.
