The UNLV interviews are laid-back and enjoyable. You have to remember that their first class just started a couple of months ago, so they are still working out kinks in various areas.
Furthermore, they aren't moved into the actual dental school yet. The dental students occupy two buildings on the undergraduate campus, and offices and classrooms are composed of dividers, etc.
The new school is huge, and it will be very cool. The current students love the awesome curriculum that UNLV is putting forth, and they seem to be enjoying their classes. The class is split into two groups, and one group is doing the sciences, while the other group is focusing on professional issues (ethics, business practices, etc.). When the semester is over, the two groups will switch. Once the school moves into the new facilities, they will divide the class into three groups and there will be three tracks running at the same time.
I hope this helps somewhat. And by the way, when the interview letter states that guests are welcome, they really are! My interview group had several spouses there. As I said, the dental school currently occupies portions of two very small buildings which are side by side, so there really isn't any way to get lost.
Let me know if I can be of any further help!
