If you are going to the Family Circle Cup, I have some suggestions regarding the weather: Prepare for every type of weather. The sun can really blaze during the day, though some days are unusually cool. Some nights are comfortable, while others--when the wind blows--are very cold. Tornadoes sometimes hit the area during mid-April, so there can be an excess of wind. So bring a lot of layers, a raincoat, perhaps a windbreaker, and--of course--a hat and plenty of sunblock.
The first year I went, I didn't have enough warm clothes, and I was miserable at night. Two of the years I have attended, there were tornadoes. One of them hit shortly before the finals began, and conditions were as windy as you would ever see them during a tennis tournament.
The stadium and grounds are quite nice, and there is shade to which you can retreat.
