Beach sunbathers might appreciate this vodka cocktail (3,6)
I believe the answer is:
sea breeze
I believe this is a double definition.
'beach sunbathers might appreciate this' is the first definition.
(pleasant breeze by the sea)
'vodka cocktail' is the second definition.
(I know that Sea Breeze is a IBA Official Cocktail)
(Other definitions for sea breeze that I've seen before include "Onshore wind; cocktail" , "that creates a cool ambience around 6 [ISLE] ?" , "Vodka-based cocktail" , "Doctor" , "Gentle wind from the ocean" .)
