OP - Count me in as saying its great and you will enjoy it. Just a few things that might help you that I haven't seen mentioned in this thread.
No cameras "off stage" but they did allow us to keep ours with us, everyone just followed the rules and didn't attempt to use them when we weren't supposed to.
They take your lunch order when you check in for the tour, so its ready along with a little surprise when the group gets to the CHH.
You will be supplied with little headsets to use to hear the tour guide, don't hesitate to let him/her know if its not working right, they will fix the situation, I have read reviews were someone complained about not hearing the guide due to dead batteries, they should have spoken up and not been mad about the tour.
We stopped a few times in out of the way places when on stage so that the guide could talk "secrets" without others hearing, they are very careful with that esp when kids are around so the magic isn't spoiled.
We rode on the Jungle Cruise (always subject to change I am sure) and HM, we had a boat to ourselves on the JC, again to preserve the magic, we entered the HM through an alternate entrance, went through the normal line (moving walkway) to get to the doom buggies and met up again after the ride.
Its been a few years since I did this particular tour so hopefully others can give you a little more up to date info. Enjoy the tour, its fun!
