So, we are coming to vegas next week, what time does the museum open and what time does it close, and do we need to schedule a time to come or just come???

I recommend you to get there when they open. Especially on weekends, it gets pretty packed. You just show up and there's no reservations/appointments.

Opens at 1 . No appointment necessary.

You can look on the website, but no reservations. Tour takes about an hour, but waiting outside to get in can be a wait if it's crowded. Tour will take groups of 15 at a time.

Just go. Get tickets online or purchase on window no appointment

We just went this past Wednesday. We got there around 1 and the line wasnt long at all. I believe they close at 11. You have to sign a waiver to get in and you can purchase tickets online or purchase them when you get there for $44.

You can google the opening times depending on the date that you go. In regards to scheduling, I would certainly book as wait times can be quite long, especially in October around Halloween. It's based in a first come first served booking. Choose you day, show up and they'll let you in as groups for the guided tours. Hope this helps!

Just go in. It opens at one.
