Hurries holidaymaker aboard ship (8)
I believe the answer is:
scampers
'hurries' is the definition.
(I know this)
'holidaymaker aboard ship' is the wordplay.
'holidaymaker' becomes 'camper' (I've seen this before).
'aboard' means one lot of letters goes inside another.
'ship' becomes 'SS' (prefix in ship names eg SS Great Britain).
'camper' inserted within 'ss' is 'SCAMPERS'.
(Other definitions for scampers that I've seen before include "Dashes" , "goes quickly" , "Clears off" , "Runs and skips playfully" .)
