Maybe a trained CM explaining WHY the lions don't do much more than lay around (in the wild, lions sleep 20-22 hours a day). When I went to Africa, we had the same problem seeing them do anything other than sleeping. Though we did get up really early one morning and saw a hunt - actually saw them moving that morning. Though I doubt Disney would consider letting a gazelle lose just so that we could get a glimpse of the lion running.
I have mixed feelings about this. I haven't been to AK yet, so the story isn't "old" to me - I haven't seen it once. I can see where it would be to those who have experienced it many times, but isn't it the same for many of the other more classic Disney rides - It's a Small World has been seen by many more people, many more times, and it isn't "old". Ok - to those who aren't fans, maybe it is, but to many others, it is a part of the classic Disney experience.
That said, if the story isn't really good - cheese gets stinky after a while. Maybe the cheesy storyline should be updated to not be so "cheesy" (I don't know personally if it is - I haven't seen it).
I kind of like that they included the conservation message. Sure, it's vacation, but I like learning things on my vacation - for the same reason that I just LOVE Epcot (The Land, Energy, and Living Seas) that a lot of other people consider boring. That's just a personal preference. Everyone is different.
I also like it because, having been a conservation educator at the zoo here in New Orleans, I know first hand how many people truly know nothing about the endangered species problem, the "Vanishing Animals" list, poaching, etc. If an important education message can be incorporated into a fun vacation experience, why not?
I do hope that they don't change it before my trip in 3 weeks - I would like to see Kilamanjaro in it's original form. (I did hear the dead elephant story from a Disney Institute speaker recently - the really bad experiences at the soft opening caused them to immediately do away with the dead big red - and as he described it, it was really bad).
