Vacation in alcove (6)
I believe the answer is:
recess
I believe this is a double definition.
'vacation' is the first definition.
(I know that recess is a type of vacation)
'alcove' is the second definition.
(I've seen this before)
'in' is the link.
(Other definitions for recess that I've seen before include "Pause in business, time out" , "Niche or temporary cessation of court session" , "Temporary suspension of a session" , "Enclosure set back or indented" , "Parliamentary downtime" .)
