An island booth is primarily characterized by being accessible from all four sides. This design maximizes visibility and foot traffic as attendees can enter the booth from any direction, which can enhance engagement and interaction during events or trade shows. Being open on all sides allows exhibitors to showcase products or services effectively and encourages more visitors to explore the area.

While the other characteristics mentioned may apply to certain exhibit structures, they do not define the primary nature of an island booth. For instance, being surrounded by walls or combining elements of peninsula booths might describe different types of booth designs, and a specific height such as spanning over 20 feet is not a unique defining characteristic for an island booth. The accessibility from all sides is what sets it apart and makes it a popular choice for exhibitors aiming to attract and accommodate a larger number of attendees.
