Hi Carly and welcome to the Disney Parks Moms Panel.
I have just checked the
Park Hours at
Disney's Animal Kingdom Theme Park for the dates of your stay and can tell you that it is currently scheduled to be open from 9:00 AM - 7:30 PM on 7 - 11 October 2016 and from 9:00 AM - 7:00 PM on 12 - 18 October 2016. (Aside from Extra Magic Hours.)
At this moment in time, the
Nighttime Experiences don't appear to be listed on the Park Schedule for these dates.
I would therefore recommend that you keep checking the Walt Disney World website periodically from now until your arrival at the Walt Disney World Resort to see if this information has been added. Once you do arrive, you will be able to pick up a Times Guide for Disney's Animal Kingdom Theme Park which will detail the times that all entertainment is scheduled to take place on that particular day.
Finally, another suggestion would be to subscribe to the
Disney Parks Blog as this is the other place that updates and announcements about Walt Disney World tend to be made.
Wishing you a magical holiday filled with memories which will last a lifetime!
Emma
