When I stepped in the first time, my first reaction was "wow, I wasn't expecting that". And honestly, that was the same reaction all my friends and family had.
Since you have the luxury of photos before you open the door, perhaps your will be slightly different, but since I've been doing this for over a year now, I can say that people still have that same reaction.
The open floor plan really works in this situation and the highlight really is the Projection Wall :) That's right, I have a projector set up to a wall and it's awesome. Can't wait for you to see it!
