NY hotels refurbished in an inconspicuous manner (2,3,3)
I believe the answer is:
on the sly
'in an inconspicuous manner' is the definition.
I can't tell whether this defines the answer.
'ny hotels refurbished' is the wordplay.
'refurbished' indicates anagramming the letters.
'ny'+'hotels'='nyhotels'
'nyhotels' with letters rearranged gives 'ON THE SLY'.
Can you help me to learn more?
(Other definitions for on the sly that I've seen before include "under cover" , "Secretly or furtively" , "With craft" , "Behind someone's back" , "Surreptitiously" .)
