If you are a beach lover, OOB is wonderful! But try to get a place to stay outside of the heart of town. Other than that, there is not much to offer in the way of things to do if you don't have children with you. Just typical tourist shops with medium/low quality wares. I will go back because I am a beach lover, but if I want to do some shopping/other activities, I'd suggest some additional research for another location. Businesses catering to tourists were friendly enough (not overly), but I did notice that the "locals" were not very friendly. Maybe we were there at an off time. (Staff at Radley's Shop N Save really need some customer service training!).
