Thanks, everyone. I don't want to be stressed before we even begin the vacation so we plan on leaving Sunday night sometime. I have no idea why I hadn't thought of rush hour traffic in Atlanta. I guess I thought it being so early in the morning, we would be fine but I live somewhere where traffic is hardly a problem. LOL
We are flying to Mexico, so will that put us at needing to get to the airport earlier? We also already have reservations to park our car at a parking lot that services the international terminal. It's called Fast Park & Relax. I don't know how I feel about leaving my car at a hotel for so long, but there may not be any problems in doing so. The only thing most of them won't drop off at the international terminal. Now we are flying Delta and I know we can checkin at the domestic terminal and make our way, but my mom will be utilizing a wheelchair in the airport because she can't walk that far. I figure it would be easier to just go to the international terminal entrance instead of using yet another shuttle to get from the domestic terminal to the international one.
