I agree. Especially because the Zebra enclosure, to my knowledge, has issues in terms of health standards for the Zebras (I believe they were/are getting sick?), effectively keeping the ending of the Safari consistently animal-free from entry into the glen till unload. The ride was designed for the lions to be the “finale animal”, as they really ought to be. The downer of a long stretch of road at the end of the attraction with very few (if any) animal sightings likely does affect guest satisfaction. Something really has to be done with the ending to make it pop once more.
I think people are now used to seeing immersive zoo environments, and have experienced drive-through zoo experiences. There are even “similar” experiences in Florida, including at Busch Gardens. While the experiences are different enough in terms of quality and immersion, the average guest sees the theming, not necessarily the things that are designed to be unseen. A boost to the ending would be very beneficial to the ride and would be a perfect “50 for the 50th” thing, if that were actually happening.
