I suspect that most of the visitors are one and doners. I see a ton of people in stand by lines and hearing people say they would not pay for that fast pass. I get a lot of looks when I explain its free. In 2006 I took my then 5 year old on her one and done. We just got done with my so called One and Done X5 and am planning trip 6 already. That being said I have helped plan about 50 One and Done's at work.
