Burudika Band in Africa at Disney's Animal Kingdom is one of the best street performers at any of the Disney parks and a must. They are located in Africa's Harambe village opposite the Tusker bar so grab a drink and have a dance. I would recommend the Tusker beer as this is a real African beer that I have had in Kenya.
Also highly recommended is the twilight Kilimanjaro safari. We have done the safari lots of times but never at night and it was amazing. All the animals were up and about and we saw so much more than during the day. I would recommend Fast passing the Kilimanjaro safari as it gets very busy but this is one of my top must dos at any Disney park.
