I cannot emphasize enough that this is a must visit, the sign is iconic, it's classic Vegas, you'd be stupid not to stop and snap off a few pictures for the memories; it only takes 10 minutes. There is a small parking lot located in the median, fits about 10 cars worth. Mid-afternoon onward it gets pretty busy, but traffic moves in and out rather quickly. The easiest time to go is bright and early in the morning when most of Vegas is just stumbling into their hotel rooms for the morning.
