Holiday nook? (6)
I believe the answer is:
recess
This clue is a double definition.
'holiday' is the first definition.
(thesaurus)
'nook?' is the second definition.
(thesaurus)
(Other definitions for recess that I've seen before include "Holiday period" , "Niche, alcove" , "Alcove - holiday" , "Closed period for parliament" , "Holiday - nook" .)
