My second time there in the 5 years they've been open (first was months after opening) and i can remember most of the signage being in the same spots. Unfortunately they have way more signage to display then place to put them so a lot are still not out and hopefully that will change in the next few years as they can expand onto adjacent land. Make sure to purchase your tickets in advance. It is a nice small group tour narrated by a tour guide that gives you back story of when, how and where the signs came from and how they were made. Great for history lovers of old Vegas.
