I love driving down to Atlanta for a weekend getaway. I'd be very interested in hearing from everyone.
I stayed at the Renaissance downtown. It's close enough to walk to the downtown area, but still away from everything. I loved it, excellent service (room service and concierge). Great view of downtown from our balcony; wonderful beds.
I've eaten at the Sundial Restaurant a few times; proposed there last Feb. 10th... Rotating restaurant on the 72nd floor of the Westin Hotel. Some say it's overpriced, but I think it's reasonable for a good quality steak place. The money is worth the view of the city as the sun sets.
