I recently purchased a zoo membership again since its been a few years since I've been to the zoo with my two kids and they are a great deal. You can't beat $85 for a family membership - the only place similar was the Children's Museum but that closed while they relocate.
It was unseasonably warm so the Rainforest was slow. Not much has changed there in the past decade but the smell has become increasingly present. Kids had a great time and the Orangutans are amazing.
The zoo was severely understaffed for such a busy day. I could list all of the bottlenecks but I would ramble on too long and I'm sure we all have been at an understaffed event. Our day ended at the overcrowded tram station with some lady yelling that our car cut in line so our whole car was rudely told to get off. Needless to say my daughter was hysterical that 'that lady was mean and kicked her off the tram.' Time for a nap in the car.
I'll be back but probably in summer when they have more staff.
