This was our 1st time at the neon museum and we wanted to go during the day since only 3 signs are lit up at night. It's an hour long guided tour of many old and some not so old Vegas signs. The guide gives an interesting history of the signs. We called and got our tickets the day before. If you want to go at night, call ahead. When we were there some people wanted to reserve tickets for a night tour and were told there was a 2 month wait.
