Most of everything has been covered so far but the beach/beach bars are going to be a shitshow this weekend for obvious reasons. Places like red dogs and 22 north are going to be packed and an ordeal, I'd stick with Lagerheads/Neptunes/Jerry Allens. Depends on your group/size but it's probably worth checking out downtown Wilmington for at least one night. There's a lot of cool bars down there. I like the area near Husk/Blue Post/Duck and Dive and usually stick around there during holiday weekends. There's a concert series on water street all summer but it's a coldplay cover band this weekend so I won't exactly recommend that. But it's an excuse to drink outside in good weather before rolling into the surrounding bars. If you head that way check out the cellar afterwards, it's a pretty chill spot.
