My next trip is planned for September. I have only ever been to WDW during Spring Break or late May/early June. It looks like crowds are historically less in September? Will the crowds be much lighter? Will it make it easier to do more and therefore spend more time relaxing at resort?

On a related note, does the DDP make it more crowded or less pleasant in restaurants? Or does the relative lower crowd compensate for that?

Are there any other positives or negatives to this time of year that I may not be thinking of?
