Absolutely spectacular.  The beginning can be hectic since everyone goes in and out the same theater door. And the emergence room can be  busy.  But waiting to enter and exit the atrium is very understandable and very worth it. You can spend countless hours here. The perfect indoor place for short legs.  This is butterfly care and science at its best.  The bees,  ants an aquarium are a great plus to the visit. Heads up - Atrium is warm and humid but beautiful.
