Okay, I've been thinking, and heres my idea to put all the ideas together. You enter the Forbidden Forest and meet your two tour guides, Hogwarts students getting extra credit for their Care of Magical Creatures Class by leading tours. While you walk through the forest, they give a little history on the Forbidden Forest and Hogwarts, give an intro to the animals you'll see, and point out the Whomping Willow and Black Lake you'll see in the distance from the trail. You then meet the Hippogriff. At each animal, the guide will give some basic info, as well as answer questions. All in all you'll spend a few minutes at each creature. For the Hippogriff, you'll have to bow in order to move on with the tour. You then continue to walk along the trail and see Unicorns, bowtruckles, Fluffy, etc. You also meet a herd of centaurs, who you are able to ask questions to, a la Turtle Talk. You also hear a car honking, revealed later to be the flying Ford Anglia, whose car door opens and shut to look like waving. You then move into the more dangerous section. Animals there include Dragons, and the acromantulas, who you are again able to ask questions to, since Hagrid is so friendly with him, and Thestrals. The Thestrals could be taken one of two ways. Either A) you just see an empty field, and they explain that no one can see thestrals unless they have seen death. If people on the tour claim they've seen someone die, the guides could say they must have escaped again, and that they didnt notice since they themselves can see thestrals or B) use animatronics and explain a reason why people could see them. You also see Blast ended Skrewts, locked up tightly in a cage of course. At the end you enter a huge circle with an example of many of the creatures (excluding the centaurs, acromantulas, Fluffy). There would also be carts selling Butterbeer, Pumpkin Juice, etc, and benches for people to sit on. When a tour ends, the guides stay there to enter questions, and leave to go back to lead another tour when the next group returns.
