I believe it was at 8:30 pm, outside at the firepit. If you walk in the front doors of AKL straight through the lobby, and out the other end, the firepit is there on Arusha Rock.
Sometimes the time and location of the storytelling varies (due to weather, time of year, CM availability, etc.). When you check into your resort, you will get a resort newsletter. The storytelling times should be listed in there. If they're not, inquire of any of the Front Desk Cast Members; they should be able to tell you the latest details.
