Coco and Daytona are about an hour away. New Smyrna is a little more than an hour but a much less busy beach. On the gulf coast about an hour and a half away is Clearwater which has some great beaches too.
If you want to stay local there's a lot of shops, shows, and places to go. Like someone else said, if you have an idea in mind of what you enjoy doing and/or how much you want to spend doing things it would help us give you some direction.
