I believe so. Remember with the daylight savings time change it will start to get dark before 6:00. I did see on the WDW site that for the end of October, it showed park closing at 7:00, spectromagic at 6:00 and fireworks at 7:00.
Keep an eye on the park hours and parade/fireworks schedules. Right now, they don't have the fireworks listed that week. Spectromagic is up for a couple nights, but they may still be working on the new fireworks schedule. They may only have them one or two nights that week.
