There have been no e-nights in September since 9/11. You really don't need it. The crowds are very low. And, even with the shorter park hours, we have never had a hard time seeing all attractions. It's a bummer to not see MK at night, but usually there's a late night for Spectro on Saturday. Expect that night to be very crowded. Plan to go to see the parade and nighttime lights, but not to ride. Have fun. We'll be there 9/5 - 9/14.
