Stick around in Benidorm (3)
I believe the answer is:
rod
'stick' is the definition.
(I've seen this in another clue)
'around in benidorm' is the wordplay.
'around' says the letters should be written in reverse.
'in' indicates the answer is hidden within the clue.
'dor' is hidden within 'benidorm'.
'dor' backwards is '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" .)
