Bob Sehlinger, a Lowell Thomas Award-winning journalist, is best known as the creator and producer of The Unofficial Guide series.
He is credited with being the first to apply research techniques from the fields of operations research and statistics to travel guides. Among other projects, he was able to develop mathematical models that could save theme park patrons more than three hours of standing in queue in a single day.
Bob Sehlinger is founder and co-owner of Keen Communications, a book publishing company that includes Menasha Ridge Press, Clerisy Press, and Wilderness Press. The author of 27 books, Sehlinger is a past president of the Publishers Association of the South, and has served at the invitation of the U.S. State Department and the U.S. Information Service on educational missions for publishers in Hungary, Romania, and Russia.

A lifelong Disney theme park fan, Len Testa co-authors The Unofficial Guides to Walt Disney World, Disneyland, and Britain’s Best Days Out. In grad school, Len’s master’s thesis described new computer techniques for generating efficient theme park touring plans, for which Len was awarded a U.S. patent.
These days, Len leads the team at TouringPlans.com, the website and research arm of The Unofficial Guides. Len has stayed at every Disney hotel, experienced every Disney ride, and eaten at every Disney restaurant and food cart in the U.S. When he’s not at a Disney theme park, Len lives in Greensboro, North Carolina, in a mid-century modern house whose kitchen was custom-built after one of Space Mountain’s post-show scenes.
