My hubby & I will be in Lexington with our daughter & one of her college friends (the girls are 21) over Derby weekend. We were thinking about going to Keeneland to watch the Derby, I see that there are many options different floors, rooms, as well as the Derby bash in the barn. We'd love some advice! Which area is the most fun? Is tailgating the thing to do? Or is one of the rooms/parties the way to go? Also, do people dress up (dresses? hats? suits/ties?) or is it t-shirts & jeans?
