I just started considering a DL trip (our 1st) in Sept. I know that at WDW, Sept. after labor day weekend is about the quietest time of year. But I read that Sept. is "moderate" season at DL? Is this true? It will likely be our only trip ever to DL, so I don't want to go at a time when it will be crowded. We would be there Sept. 16, 17, 18 and 19 (Th.-Sun.) What do you think?
