Atlanta's is $69 on CityPASS site. It's $62.99 through Costco.com. I received my link to get the vouchers about 15 minutes after placing the order. You then take that voucher to the first location you want to visit. They will give you the remaining passes for the other locations. All must be used within 9 days of FIRST place visited. Voucher expires 6 months after order date.
CityPASS site states their rates will be going up on March 1.
