Take a photo caravan tour. It'll cost you about an extra $90 per person but is well worth it as you are driven all around the wild animal park where regular foot traffic can't get to. Take the Asian themed tour (the one where you get to feed rhinos) as you'll get to pass through all of the Africa exhibits on your way to Asia. We were lucky and had a giraffe come right up to our truck to say hello. After passing through Africa, you get to hand feed Indian Rhinos. These docile creatures don't hurt at all as you feed them apples from the truck. They have a big squishy tooth in front that feels a little gross but it ends up being a really nice experience. The guides were excellent and extremely knowledgeable. Highly recommend. Good for adults and little kids. Bring ear muffs or a hat in winter months as it gets fairly cold and blustery on the savanna.
