We saw this place on TV and would have never even known it was here otherwise.  So of  course, when we were town for our honeymoon, we had to make a little trip out to the museum.  Note:  It's very close to the Old Vegas/Fremont area.  We did not book tickets in advance, but drove up and they had openings for a tour 30 minutes later.  It's an hour tour and you get to see all Old Vegas Neon Lights and get to hear about the history of the lights/signs in the town.  My favorite signs were the Sahara Casino sign that was recently added.  They do offer discounts for military, student ID's, or NV residents.  It's a non-profit, so proceeds go back into the musuem.
