I loved it too! The guides were great and pretty much memorized everyone's names immediately so would call us by name.
Everything you have with you needs to be attached to the vest somehow. They will hook up your sunglasses straps to hang around your neck. For my phone, they were able to loop a strap through one of the openings in the case. I saw someone else had a large DSLR camera that they made sure was secure with a neck strap. You also get a metal water bottle (which you keep), and hooks to your vest. They have lockers at the entrance for you to store anything else. It will be about 2 hrs into the tour before you have access to a bathroom, so keep that in mind (but the guides make sure to remind you when you check in).
The tour starts going through the front half of Gorilla Falls trail, and the guide will give you info about some of the animals (you have headsets and they have a microphone). Then you duck in a side pathway, which leads to the hippo areas (we were able to pause to get a good view of a zebra). When you go out over the ledge, it is for the male enclosure (the males and females are separated), and we had a keeper there feeding the hippos so they both came up really close. Then you have a brief "hike" through the woods to the overhead bridges, which go over the female hippo and crocodile areas. The bridges you go one by one, so you don't have to worry about being jostled by someone else walking up behind you. Then there is the crocodile lookout.
For the savanaha, you follow a similar path as the Kilimanjaro Safaris, but your truck can stop at the side and wait for a bit, especially if there are interesting animals around. After you pass the elephants, you have food at the boma and I think its about a 30 minute break which gives you a great chance to observe everything. The food was wonderful, and I am extremely picky, so that's saying a lot! If you ever want one of the guides to take a photo of a specific animal or of your group, just ask!
You then get back on the truck and finish the Safari route, going by the cheetahs, lions, etc. And you get let off near the Rafiki Planet Watch train, where you pick the animal you want to give part of your money to. And then they give you a card with a code on it for access to your photos (one card per group).
I loved it so much, I will be doing it again in December!
