Flight
If you want to avoid the headache of flying into the Atlanta airport, I would recommend flying into Birmingham. We live 5-10 minutes away from the Birmingham airport and 2+ hours away from Atlanta. You'll have a harder time finding DIRECT flights into Birmingham, but also, I've never openly wept in the Birmingham airport, so... don't say I didn't warn you.
Hotel
I've reserved a block of rooms at this hotel for about $120/night, but there are cheaper options available. Home hospitality could also be arranged with enough notice. This hotel is about a 13 minute walk from the Temple Beth-El (where both the wedding ceremony and the reception will take place), but parking is also available at the hotel for $10/night.
