What a beautiful place if you love butterflies! My daughter is a little young for the exhibit (10.5 months and not walking yet) but we still had a great time. The conservatory where they keep all the butterflies is really humid, so I would dress lightly. There's a great 3D movie that teaches you all about butterflies, I hope to be able to watch that one day. If you have little ones, you can't bring your stroller in the conservatory so I'd suggest a baby carries or wrap and make sure to watch where you walk because there are literally butterflies everywhere :)
A very magical and enchanting place for children and adults, reminded me a little bit of Jurassic park! We ended up getting the year combo pass here & the Aquarium to make it more of a day trip because it made sense if you go at least twice.
