Hello, we are visiting the area for the first time! We are a family of older teenagers, youngest is 14. Any suggestions for the area? We do like outdoor adventures. Deep sea fishing? Sea Kayaking? Also, I heard the restaurants/stores in the area only take cash. Is that correct or do restaurants take credit/debit cards? Thanks for your help! PS we are staying in a condo. Any grocery store recommendations that are a bit cheaper? Thanks again!
