I didn't go to the open house, I really don't think you'll miss much.
I just did a tour with Michael Heck. She's great and will be able to provide just as much information as you'd get elsewhere. Also, depending on when you're coming, you might want to try to sit in on a class.
Like I said, if you have any questions let me know. PM would probably be best since I don't check this board often.
