What is the difference between tiers for event tickets?

The Show is for 18 years and older only and evening only. They do this little interactive theater type thing which is kind of corny and annoying. But if you don't want to participate in that you don't have to. When I went I just broke away from the theater experience and explored on my own and it was no problem. If you go to the Museum experience, it is during the day children are allowed in and there is no interactive experience involved.

Basically you get access to different experiences. The info about each on the site is quite good.
