Destroy resort and tower (4,4)
I believe the answer is:
tear down
'destroy' is the definition.
(tearing down is a kind of destroying)
'resort and tower' is the wordplay.
'resort' indicates anagramming the letters.
'and'+'tower'='andtower'
'andtower' is an anagram of 'TEAR DOWN'.
(Other definitions for tear down that I've seen before include "trash" , "Level" , "Demolish" .)
