Huge place with lot of things to explore. Its hard to see the entire place in a single visit. IMO regular tickets are over priced..however the free admission Wednesdays are a good deal.. all special exhibits are a must at least once except the butterfly garden..they don't have a lot of them flying around..most of them sit on the plants and it's very hard to differentiate and identify them.. overall it's a good day(s) trip.
