Ladies sleep here and there in corridor (5)
I believe the answer is:
aisle
'corridor' is the definition.
(I've seen this before)
'ladies sleep here and there' is the wordplay.
'here and there' indicates alternate letters (here and then can mean regularly).
'ladies'+'sleep'='ladiessleep'
The alternating letters of 'ladiessleep' are 'AISLE'.
'in' acts as a link.
(Other definitions for aisle that I've seen before include "Supermarket section" , "Way between seating areas" , "A key" , "Part of supermarket" , "Passage down the side of a church nave" .)
