We told our girls we would do this on our June trip, so I'm checking options. Saw the $50 discount (per person, so $200 savings for us) if you do the afternoon treks (11:45 or later). Hard not to be tempted by that kind of savings! I fully understand the whole "see more animals in the morning than in the afternoon" approach, due to the heat, etc. I guess my question is how that theory plays out on the Wild Africa Trek. We will have done the regular Safari ride at least once (probably more) during the same trip, so we will have seen plenty of animals from a truck. Is the truck tour part of the Trek a lot different than the normal Safari version? Are you getting closer to the animals during the truck part of the Trek? I know there is also the walking part where you're on a bridge over the hippos and crocodiles, etc., but neither of those two groups is usually very active anyway, so I don't see a lot of difference in morning vs. afternoon for that particular part of the Trek...but if the Trek allows you much closer access to other animals, then we'd be more inclined to stick with a morning time, even for the extra cost.
