I went last year Sept 23-30. Great time of year to go, and I'm thinking of going again this year-thinking so much that I even wrote the 7 month date for September 20th on my calendar, and I've been looking at airfare for the latter part of September. Right now, airfare from our airport is so high, I've only looked. But I wanted to tell all you September travelers what a great, low-crowd time you've chosen.
