Pick your stops and your party. This adds up admission and parking from what each venue publishes on its own site — and counts, rather than guesses, the ones that publish nothing.
Why the total is a floor, not a price
Of the 304 Georgia venues in this dataset, 95 are free to enter. Of the rest, 151 publish no adult admission price at all on their own website. For those, a family cannot find out what a visit costs without phoning or entering a booking flow.
So this calculator does something most price tools refuse to do: where a figure is not published, it says so and leaves it out of the arithmetic, rather than filling the gap with an average. A total of $40 with two unknowns attached is honest. A total of $58 built on guesses is not.
One assumption is made and marked rather than hidden: where a venue publishes an adult price but no child price, children are counted at the adult rate and the line is flagged with an asterisk. Many Georgia venues genuinely charge one price for everyone, so this is usually right — but it is an assumption, and you should be able to see where it was made.
Among venues that do charge and publish, the median cost for a family of four — admission plus parking — is $20.
