Okay, I see what you are indicating. The parking spaces within the driveway "loop" are indeed all not much farther away from the entrances (for main programming), yet far enough away to make an impact on the crowd. Although we'll still be having to deal with people walking back and forth from one side of the "loop" to the other. That may be a point of resistance for approval as far as the hotel in concerned as the foot traffic would be going right across the part of the driveway that the shuttle buses, arriving/departing guest, etc use. Safety concerns being a major one of those reasons. Another reason is that is also the side of the entryway where the doorman's outside station/desk is located and they may not be happy about a smoking area nearby (you'd need to use the parking spaces farthest away from the entry).
I haven't kept up on the hooka situation. If those are still a problem in terms of taking up space, could it at least be suggested they move elsewhere? There is a difference between wanting a close area for a quick smoke and a "social gathering" smoke.
Would it be viable to ask that "social group" smokers locate themselves somewhere else and for the rest of us to campaign to have a temporary (ACen weekend only) parking lot spot?
Another "catch" here is just who is using those parking spaces... If the hotel has some sort of vested interest in reserving them for someone specific or not. Plus the resident duck that hangs around those spaces may not like it either. Quack.
Those spaces are in use and there is a need to keep them.
