Country inn, a great resort (9)
I believe the answer is:
argentina
'country' is the definition.
(I know that Argentina is a country)
'inn a great resort' is the wordplay.
'resort' is an anagram indicator.
'inn'+'a'+'great'='innagreat'
'innagreat' is an anagram of 'ARGENTINA'.
(Other definitions for argentina that I've seen before include "Ta, Grannie, for the odd country" , "Republic" , "Song from 'Evita' - 'Don't Cry For Me . . . . . . . . . '" , "Home of the tango" , "state" .)
