We (family of three with a teen) live about six hours from Atlanta and have been a few times (including once last fall for an all day trip - great fun). My husband also attended Georgia Tech for part of his undergrad. We're coming up for a long weekend in late March (four nights). We'll be in town from Friday evening until Tuesday morning. Saturday, our daughter has a college visit at Oglethorpe. Sunday is for Six Flags (we have passes). Monday is open. We'd like to take a look at Agnes Scott, go to IKEA (we should be closing on a new house soon), and definitely hit a few "big city" items like Whole Foods because we live in a small coastal town.
As far as hotels, we like Hyatts, Hiltons, Westins. We love the Omni hotels too. We're not opposed to independent places as well. I like places where if something does go wrong, it will be taken care of. My husband loves having a package with breakfast and really loves hotels with concierge floors. We also like places where we can walk to restaurants and shops. We will have a car but once we get back to the hotel, we like to be able to venture out on foot. As far as price, under $300 with everything would be good.
Based on all of that, I've come up with the Westin Buckhead (only place I can find with concierge on the weekend), 12 in Atlantic Station, and two independent hotels - the Artmore and the Georgian Terrace.
Any other suggestions or advice?
