Stick around in Benidorm (3)
I believe the answer is:
rod
'stick' is the definition.
(both can mean a pole)
'around in benidorm' is the wordplay.
'around' is a reversal indicator.
'in' indicates the answer is hidden within the clue.
'dor' is hidden in the letters of 'benidorm'.
'dor' written backwards gives 'ROD'.
(Other definitions for rod that I've seen before include "pistol" , "Measurement" , "Long bar or pole" , "Former measure equal to a quarter of a chain" , "something fisherman brings home" .)
