Promotion offers exciting experiences (10)
I believe the answer is:
adventures
'exciting experiences' is the definition.
'promotion offers' is the wordplay.
'promotion' becomes 'ad' (ad is a kind of promotion).
'offers' becomes 'ventures'.
'ad'+'ventures'='ADVENTURES'
(Other definitions for adventures that I've seen before include "Exploits" , "Tuned raves (anag.)" , "exciting experiences?" , "Dangerous undertakings" , "Alice's - - in Wonderland" .)
