16,000 people can ride Pirates by 3pm on a summer day. My point is that 1,300 or even 16,000 people signed the online petition, it's still an extremely small number to Disney.
And further than that, it's not only a small number, but it's a small number of people who aren't Disney customers. Yes, someone who signs a petition about the Peoplemover is more likely to be a Disney guest than not, but it costs nothing to click "I support this" when it's presented to you online. That doesn't tell Disney anything about people who would actually travel out to the parks to see a new Peoplemover. Like I said, if you want to make any sort of impact you should go in person to City Hall and tell them how you feel.
However, a quick google search gives this: http://www.ultimaterollercoaster.com...gi?read=178998. In 2006, 14 million people went to Disneyland. Quite a bit more than 16,000, huh?
