We went the last week of September in 2005 and it was wonderful. The value rates are still in effect (they end October 2 and go back to regular rates), the weather is great, and you can go to the Halloween party at the end of the week if you want. Plus the free dining. Also, the crowds are lighter (there are none) because no one is out for fall break yet. Have a great time! We will be back there the last week of September this year- there is no better time!
