Another year, another attempt at unisex restrooms

In Atlanta last year, the ASA attempted to provide unisex restrooms.  The only problem that I saw with this was that all of the unisex restrooms I saw had originally been women’s restrooms.  In Las Vegas, the ASA tried unisex restrooms again, as seen below:

Again, I appreciate the attempt at progressiveness, and I realize that this is sort of a “damned if you do, damned if you don’t” situation, but I wonder if anybody actually treated these restrooms as unisex since they were right next to each other.  Did anybody use the restroom (or see somebody using the restroom) that was originally designated for the opposite sex?  If not, I wonder if people would have been more likely to treat the restrooms as unisex if the original signs had been covered.
