What's missing in this hotel room?

I went to a conference at the Gaylord Opryland Hotel a few weeks ago and just flipping through the pictures I took of my room.  It's a fairly standard, modern hotel room, but I realized that something was missing.  I'm wondering if you notice what I did...

 The room had no art.  Thinking about it, the only art I can remember in the entire hotel was a massive Chihuly piece in the lobby (I like Chihuly) and some pretty paintings in one of the restaurants. 

The overall feel of the conference center is surreal.  I don't think I stepped outside until the final night of the conference.  Some people were calling it a biodome.

 

That's a two story restaurant on the right side.

Taken from the balcony on the 2nd story of the restaurant in the first picture.

They had some interesting decor ideas.

The food was pretty good for a conference center.  I went to a nice cocktail party and a wonderful group dinner at one of the restaurants.

This conference is being held at another Gaylord conference center next year (in Orlando).  It'll be interesting to compare properties.

I believe Blogher or She Blogs or one of those blogger conferences was at this place a while back.  Did anyone go?  What did you think of it?
