My suggestion is just purchase the City Pass. Saves you money in the long run.
You can go to the actual Pemberton Place for free but going into the Aquarium and Coca-Cola World needs a ticket. The Aquarium is "$32.95 for adults (ages 13 to 64), $28.95 for children (ages 3 to 12) and $30.95 for seniors (65 plus)" according to the Georgia Aquarium (there may be special Mother's Day prices) and for Coca-Cola the prices are $17 for adults, $15 for seniors, and $13 for children. Parking for Coca-Cola is $10 for the day and Aquarium parking is $12 for the day.
