The Okapi are only at Kidani Village, and only in the area outback beyond the pool. Definitely worth the short walk. The pool areas are also very cool to check out. IMO, the main animal viewing area off of the lobby at Kidani is better than at Jambo. Seems like we see animals more consistently there, and I feel like they are closer. It's so easy to travel between the two sides of the resorts, no reason NOT to do both!
