Hi Michelle , I was there last week and I think the notice read... suggested donations 20-30 dollars per adult. Not sure about kids.
We were all adults. The ticket was 25$.
You have a pay what you wish option. (You can pay whatever you want) and buying tickets from 25$ on. With these tickets you will be able to enjoy the main attractions and special exibitions.
Adults are 20-30 dollars and kids I believe were free. Another person mentioned it's a donation but I highly doubt it and did not see anywhere mentioning it's a donation. They check your tickets before letting you in
