We're staying at AKL, too. I'm so excited! You'll find an activities schedule at the resort when you check in. They note times for feeding flamingos, cultural presentations by CMs from the countries they live, Boma and Jiko combine for a short culinary tour with a small sample of food served, nightly movies, campfire, pool activities, etc. These are all included in the stay. Other activities will have a fee.
I tried to attach May's schedule but it's not working. Google "animal kingdom lodge activities May (or June) 2019" and you should be able to find a PDF.
