We loved it so much that we purchased annual passes. I will say though, that a one day pass is a lot of money for what you get. You can only stay in the butterfly atrium for so long. On the inside of the wonderland there are a few reptiles and fish (that's it). Now that the new aquarium is open right next door, maybe they should find something different to do with that room?! The 3D movie is amazing, and never seems to get old.
I do like that they have special events like painting and yoga within the wonderland (at an extra cost). It is super relaxing and mesmerizing to walk through the atrium. I'm glad I purchased the annual pass.
