There is no online option for buying tickets at this time.
Yes. You can go their website and buy them. We did when we were down there
I didn't see an option to buy tickets online when I went there with my daughter. They did have two lines for tickets (there was no wait when we got there). Their 'entrance process' is fast, maybe two min, so it wasn't a big deal to get in. What was hard was figuring out what to do first. This children's museum is awesome.
