Take a break, with opportunity to get cottage in US (8)
I believe the answer is:
restroom
'cottage in us' is the definition.
(cottage can informally mean a public toilet)
'take a break with opportunity' is the wordplay.
'take a break' becomes 'rest' (to have a rest is to take a break).
'with' says to put letters next to each other.
'opportunity' becomes 'room' (room is a kind of opportunity).
'rest'+'room'='RESTROOM'
'to get' acts as a link.
(Other definitions for restroom that I've seen before include "John" , "Where some may have recovered" .)
