What does "block" refer to in event planning?

In event planning, the term "block" specifically refers to reserved accommodations or spaces. This concept is commonly used when planners arrange hotel rooms, seating for an event, or other necessary venues to ensure that a group has access to these resources during their event. For instance, a hotel might offer a block of rooms at a discounted rate for attendees of a conference, allowing for easier coordination of lodging and ensuring a sufficient number of rooms are available for participants.

While other options relate to different aspects of event planning — such as budget management, venue design, or registration processes — they do not capture the essence of what a "block" signifies within the context of managing event logistics and accommodations. Understanding this term is crucial for effective event organization and ensuring smooth operations for group attendance.
