You wouldn't believe the lines at the Georgia Aquarium. If you order your tickets online (on their website) they place you in time spots where you have to enter during that time, you can show up and by tickets but aren't promised tickets, you can get tickets through a hotel package (view here, http://www.georgiaaquarium.org/visitUs/hotelPackages.aspx), or you can buy the City Pass. If you buy the City Pass or buy the hotel package the tickets aren't timed which means you can go in at anytime. We got there at 7:30 in the morning (got up at 5:30, blah) and we were the first ones in line, but in 30 minutes (8:00 a.m.) the line was almost out in the street, it was CRAZY. It's a great place though, please check it out. You'll need to come back and check out the new World of Coca-Cola next year, it's going to be a great place (replacing the old World of Coke over on MJK) Let me know if you need any more information about Atlanta like where to stay, etc. - I can help you get a deal. I've got some friends in North Atlanta hotels, and some others around Atlanta. :)
