The Neon Museum is by far my favorite! A quick note, it pairs great with the Mob Museum because of how much the history overlaps. You are taken on an hour guided tour by a docent. They are very knowledgeable and each one tells it a little differently so you can go multiple times and learn different facts each time. They have their favorite signs and may share more facts than other signs. They have day and night tours. It is outside so keep the weather in mind. They are great with safety and do a great job keeping everyone safe. I have been to the Neon Museum 2 times already and plan to go back again. I always recommend the museum to anyone who asks what to do in Las Vegas. Since it's a little further north, a lot of people don't know about it. But it is popular and the tour groups have a limit so make sure you get your tickets in advance. Both tours I've been on were sold out prior to the tour day so plan ahead!
