Scottish town, some holiday resort (3)
I believe the answer is:
ayr
'scottish town' is the definition.
(I've seen this before)
'some holiday resort' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'AYR' is hidden within 'holiday resort'.
(Other definitions for ayr that I've seen before include "Race course" , "Scots port on Firth of Clyde" , "Scottish resort" , "Scots. town; sounds like song" , "Scottish seaport" .)
