Only played the multi-player maps but feel they have been designed in a lazy manner. Doors - they are either open or closed, you can't interact with them. Large areas that in some cases are literally roped off in the game that you should be able to get into but can't. The reception desk, nope, that's also just for show, don't think you can hide behind it.
Overall leads to a feeling that you can walk round the map, but not really experience the map and interact with any elements. Graphics are beautiful but game play is what you may have got 10 years ago.
