Hey Mr. Cody,
This is magical! A Harry Potter simulation was the first thing that came to my mind when I heard about VR for the first time. I have one quetion. Are you planning to make a entire map of Hogwarts, which people could walk through and explore. If so I suggest you to watch this youtube video:

its is youtube video made by Shadiversity he could possibly be of some help when creating a full Hogwarts recreation if thats what you intend on doing.
Much respect
