Yes, and their "interviews" are lame and a complete waste of time, other than to see the campus first-hand. They will NOT get you a better chance of admissions.
Meeting with the Dean won't get you a better chance, nor will meeting with Dr. Ayers.
So if you have the money and want to see what the campus looks like, then I suggest you visit it. But if you are going out in hopes of increasing your standing with the adcom, don't spend the money because it won't help at all.
