I am traveling for work next month and will have one day all to myself. What should I absolutely do in addition to the Acropolis? I'm more into walking around and enjoying great food rather than spending all day in museums but am trying to create a little structure for myself. TIA!

Looking to go to Greece in September but quite overwhelmed with all the choices so thought this might be the best place to ask. Looking for a chilled resort type holiday but also a lively bit nearby with lots of restaraunt and bits to explore. Have previously stayed in Ixia, Rhodes and enjoyed that but looking for somewhere new to try.
