Bill Zanetti is a consultant for the theme park industry, and teaches several theme park management courses at the University of Central Florida in Orlando. With a specialty in queuing theory, Bill seeks to improve the way that people move through theme parks and wait in line for attractions. In this interview, Bill discusses the difference between mandatory and voluntary queueing, and highlights instances where venues should focus on efficiency versus distractions. Bill believes that there is an optimal time for every attraction for how long the queue should be, meaning that having no wait is not always the most enjoyable experience. And when asked about the future of queueing, Bill believes that no matter what type of queue structure is in place - including standby lines, virtual queues, or expedited entry - every guest should have the opportunity to enjoy an attraction, regardless of when they arrived at the park or if they were able to obtain a virtual queuing position.
