I think we can really break down the idea of overrated exhibits into two categories. The first category is exhibits in which the quality of care and/or animal welfare are debated- such as the Tropic World Great Ape habitats being discussed. The second category is exhibits that are overrated due to visitor needs/expectations not being met, such as the Arctic Ring of Life example from
@birdsandbats. I'd like to propose another exhibit complex that fits solidly in this second category: Kilimanjaro Safaris at Disney's Animal Kingdom. While I am not denying that the exhibits are a great size and provide excellent homes for the elephants, giraffes, rhinos, hippos, and other ungulates, there are a few places I feel this exhibit falls short. Number one is the limited time allowed to view the animals. I know this is a main criticism brought up on this site before, and I think it's extremely valid. Especially with having to wait an hour plus to ride this ride, it's disappointing when such short amounts of time are allowed at some of the exhibit space- sometimes not even stopping. Furthermore, there's definitely a lot of luck into how good your visibility is. For example, if a certain species is best viewed from the left side of the truck, if you're seated on the right side of the truck it may be difficult to get a decent view of the animal. It'd be great if there were opportunities to see these animals for a more prolonged period of time, especially for some of the more unique opportunities. This especially feels like a shame when discussing the hippos. Disney's Animal Kingdom does perhaps the best job of any US zoo in hippo management- by keeping them in such a large bloat and having both land and water areas of a decent size. It'd be really great to be able to see this hippo bloat for a longer amount of time, as it'd be really interesting to observe the behaviors and interactions of these animals as they'd be found in the wild- something few other zoos are able to replicate. However, the safari ride allows less than a minute to see the hippos, and the hippo exhibit on Gorilla Falls Exploration Trail is completely separate from the Kilimanjaro Safaris habitat- so doesn't allow the same opportunity to see a large bloat of hippos. That's not even mentioning the species only visible from the Safaris- which include everything from ABC crowd-pleasers (African Elephant, African Lion, etc.) to ungulates (sable antelope, bongo, springbok, etc.) and even some birds and primates (saddlebill stork, pink-backed pelican, mandrill). Even if the zoo wanted to leave a few of these exhibits as safari ride exclusive, it'd be nice to see a few opportunities to see some of the habitats by foot. Furthermore, to a lot of people the ride may not be enjoyable due to how bumpy it is, and if somebody wanted to see certain animals, but couldn't/didn't want to ride due to motion sickness, etc. it'd be a real shame. So, in essence, this is an exhibit that, while great for the animals, is less enjoyable for guests, or at least those who are more zoo-oriented.
