Secret American resort (2,6)
I believe the answer is:
in camera
'secret' is the definition.
(legal term meaning in private, lit. 'in a chamber')
'american resort' is the wordplay.
'resort' indicates an anagram.
'american' with letters rearranged gives 'IN CAMERA'.
(Other definitions for in camera that I've seen before include "not for all to see" , "Conducted in private" , "Where film would be kept" , "Kept private (law)" , "'In private (2,6)'" .)
