Figure seen around hotel organised charity event (8)
I believe the answer is:
telethon
'charity event' is the definition.
(I've seen this before)
'figure seen around hotel organised' is the wordplay.
'figure' becomes 'ten' (I've seen this before).
'seen around' is an insertion indicator.
'organised' indicates an anagram.
'hotel' anagrammed gives 'letho'.
'ten' going around 'letho' is 'TELETHON'.
(Other definitions for telethon that I've seen before include "Television event to raise funds for charity" , "TV fundraiser" , "Long charity TV show" , "TV broadcast for charity" , "Lengthy broadcast for charity" .)
