I would recommend getting to the park about a hour before they open. Last season SFoG opened about 15 min early so that you can ride either the Georgia Cyclone or the Georgia Scorcher. I don't know if they going to let you in early this season since the park is now under RedZone! I would recommend riding the Georgia Scorcher very quickly and go get in line for the mad dash to Goliath. Also since you are going on a Monday I don't think you have to worry about the crowds being bad! Also Fearman's Manor is open year around but I think its a wast of money.
