Well - cab fare from the Airport to Alpharetta used to be about $80.

You might come out cheaper & money ahead if you can get with a transport service. They have vans and load them up with travelers, and drop them off...I found them to be a lot cheaper than cab fare.

From the Airport to Rome - I will take a fair to wild guess that you will have to shell out about $200+ for the trip and $24 for cab tip.

Is there anyone you can get to have them come get you, and you just pay them for their gas???

Good Luck!
