Of all the times Ive been to Las Vegas I have never stopped to take a pic with the sign. And we finally decided to drop by, it was at night time. Obviously the best time would be in the daytime so you can actually see the sign and the people standing in front of it. I like that they have a designated parking area and that it is "self-serve". No one there to monitor who and when people can take pics. Just take the pic with the iconic sign and move out of the way so others can take their pic.
