Holidaymaker, perhaps one offering story about endless party (9)
I believe the answer is:
traveller
'holidaymaker perhaps' is the definition.
(holidaymaker is a kind of traveller)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for traveller that I've seen before include "Person on a journey" , "'I met a . . . . . . . . . from an antique land' (P.B.Shelley)" , "fare?" , "Itinerant" , "One on the move" .)
