i like your treatment to get this to b/w - the grain is pretty good in this image but I am not a great fan of the angle of the shot - I would either like to see more of the hotel staff or less of them and focus on the people in the chairs.
good choice of subject.. looks like a vintage shot.. maybe you've not taken advantage of the architecture provided though.. if taken from near the arches it would have created a more dramatic shot..
Nice architecture for this challenge, and the viewpoint is far enough away that the clothing isn't dating it one way or another ... it's more timeless-looking from this distance.
