My DH and I took this tour in May and we loved it! We booked a 10:15 tour so that it wouldn't be too hot yet and so that the stop for food would coincide with lunchtime. We're both AP holders but the AP discount wasn't offered on the tour for this day/time. I wasn't aware prior to booking that there were sometimes exclusions, but I wanted to do it anyway so we paid the full price.
We met our guides next to the entrance for Kilimanjaro Safaris to check in and get our gear. This included metal water bottles that we got to keep as souvenirs after the tour (which DH and I both sacrificed to the TSA gods at MCO because we absentmindedly forgot to make sure they were empty before entering security... oops!). We started the tour by walking a small part of the Gorilla Falls Exploration trail with our guides. They led us onto a private/gated pathway over to see a couple of hippos up close. We met one of their caretakers there who told us a bit about them and then answered any questions we had. We were a small group of five including DH and me, so everyone was able to ask several questions. There was a girl on the tour for her 9th birthday whose question for every animal we saw was, "Can I pet it?" It was cute the first couple of times.
We kept going on the path over toward the crocodiles, which we got to see up close from a couple of vantage points including the rope bridges. I thought that part was a lot of fun. Afterward, we boarded the ride vehicle again and took a path very similar to Kilimanjaro Safaris, with our guides telling us about the animals we saw along the way (and reiterating to the birthday girl that, no, she couldn't pet any of them). We stopped to eat around the beginning of the third hour of the tour. The food was almost identical to the Savor the Savannah menu (minus the breads, nuts, and alcohol). It was enough to pass as lunch for me, but not quite for my DH.
After eating, we boarded the vehicle again and saw a few more animals before heading back to where we started.
At the end of the tour we got a code to download all of the pictures that our guides took along the way. There were a lot of photos of the animals we saw, as well as posed and candid photos of us, which are some of our overall favorites from that trip.
I think this is definitely worth doing once. I plan to do it again on a future trip to take my DD once she's a little bigger.
