October is usually pretty good as far as crowds go. However, it's my understanding that LOTS of people are taking advantage of the FTP package that was offered. I believe that there will be a goodly sized crowd there. But, the crowd will probably not approach the volume experienced at peak times, so it's still a better time for Disney to refurb rides.
Trust me, I'm going in October and I am so bummed that some of the rides are being refurbed.
