You can't go to Vegas without taking a picture in front of the classic welcome sign! In the past few years they've constructed a small parking lot (free) in the median for easy access driving southbound on LV Blvd. (the strip). I will repeat what others have already said in that there is often a semi-long line and that as such, it would be wise to keep all valuables either with you or out of ones eyesight if you must leave them in your parked vehicle. Nothing happened to me but I have heard stories of theft. Aside from these two things, the experience is a must and I'm sure you will enjoy yourself.
