We also leave three weeks from today, and I'm thanking my lucky stars that we happened to have a child born on October 17th, because we picked this week due to her birthday, not knowing about the big conventions and the PGA event. As everyone else has noted, the parks should have relatively light crowds, although the resorts and restaurants will probably be crowded. I'm hoping that the restaurant crowding from the conventioneers will be offset by the fact that free dining is not being offered that week, so the restaurants won't be any more crowded than normal, but we'll see. I did try to switch around some of our ADRs last week with no luck, but it's fine...they weren't critical changes and we can live with what we've already arranged.
