I have a Aquarium pass with Chattanooga Aquarium.They stated I would get discounts for the Atlanta zoo and Aquarium with my pass.Does anyone know how much of a discount ?

You should receive 50% of at the Atlanta Zoo and 10% of at their gift shops. The Georgia aquarium in Atlanta is not AZA and therefore gives no discount. You can visit the aquarium for 1/3 the price of you but tickets online for the evening only (meaning you can't enter until 4pm). The zoo is wonderful, but I honestly wouldn't recommend the aquarium. It just wasn't worth the price + $15 parking. I just visited and this was true for me. You can always check your discount by looking at the AZA reciprocity list available here: https://www.aza.org/reciprocity

For the Aquaruim ( I called ) no discount.

Quick phone call should answer your questions if answers not on website.

Something like $3.00 off for the Zoo not sure about Aquarium probably the same.From Chattanooga now live here in metro area

Best way to find out is check their website and or reach out to them directly.
