Ok, I just got through page 1 and haven't read the other pages.
I went the first day it was opened - March 12th and did the second tour of the day at 11am. Our tour was full (there is a DVC discount too). It was fun and nice to do for something different and only for an hour without a great deal of cost. The CM's were super excited being the first day of it. You get to go backstage (they tell you no photos allowed) and go to what they call "the berm" to view the elephants and take pics. Note that the elephants are free roaming so if they aren't near the berm and more towards the safari vehicles, you won't get to see a lot of them. The baby was out and that was cute. They did walk by close for a bit but did start to wander around so they aren't super close to you the entire time.
They have another CM who talks about how they care for them (hence the name) and you get to learn some neat things about them and how the population of them is dwindling. Part of the funds for the tour go to Disney Conservation that goes directly for the saving of the elephants in Africa etc.
If you've been a lot of times, it is nice to do for something inexpensive and short. I enjoyed it but of course it was earlier in the morning (don't know if that makes a difference) and the elephants were walking by the berm. If they aren't anywhere near, it can be disappointing as you won't see much.
