It gives vacationists pleasure around Pinner (4)
I believe the answer is:
pier
'it gives vacationists' is the definition.
The definition suggests a singular noun which matches the answer.
'pleasure around pinner' is the wordplay.
'pleasure' becomes 'respite' (respite is a kind of pleasure).
'around' says to take the centre.
'pinner' becomes 'ier' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
The centre of 'respite' is 'p'.
'p'+'ier'='PIER'
Can you help me to learn more?
(Other definitions for pier that I've seen before include "such as you might see at the seaside" , "Upright member" , "Platform built out from the shore, supported on piles" , "Building projecting into the sea" , "Buttress; landing place" .)
