You can buy the tickets in advanced. It's going to be the same price if you buy them at the door, however since the museum is a small place, they do have a limit.
I did, but it looked like they took walk ins without a problem
Not at all. Even though the museum is small, there were not much people.
I went on a weekend and had to buy tickets online to reserve a time. It's small and there's a limit, available time slots can sell out quickly. I'm just repeating everything everybody else said.
When we went, we didn't need a reservation, access was very fast and easy.
I purchased tickets at the desk. It was a Monday afternoon. Quick to get inside. SUPER FUN!!!
I was able to just do a walk-in mid-day on Friday. Weekends may be busier.
