1st timers in Atlanta. Staying at Country Inn & Suites By Carlson, Atlanta Northwest at Windy Hill Road, GA this Memorial Day weekend (5/25 to 5/27). Any advise on nice place to see in & around the area we are staying at? We will have the car w/ us the whole time, is it better to drive (I heard traffic in Atlanta is a nightmare!) or take MARTA to see attractions? Thanks.
