I can speak from our experience this past August, as we were there Aug 27 - 30th and it was, by far, the lightest we have ever had at DL. Wait times were super managable not even needing fastpasses for BTM, CS or Soarin most of the time. The best part was that they were still running longer hours and there was only one ride down (HM for the Halloween layover). The weather was warm so we could enjoy the pool, all in all, much better bang for our buck as opposed to a previous October trip where the hours were shorter and more rides down for refurbishment. DH and I have already agreed that this time of year is now our new favorite.
