Free, so vacation in province (4,6)
I believe the answer is:
nova scotia
'province' is the definition.
(Nova Scotia is an example)
'free so vacation' is the wordplay.
'free' indicates anagramming the letters.
'so'+'vacation'='sovacation'
'sovacation' with letters rearranged gives 'NOVA SCOTIA'.
'in' is the link.
(Other definitions for nova scotia that I've seen before include "Atlantic region" , "Canadian peninsula" , "Canadian province" .)
