Distinguishing feature of hotel brand accommodating everybody (8)
I believe the answer is:
hallmark
'distinguishing feature' is the definition.
(I've seen this before)
'hotel brand accommodating everybody' is the wordplay.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'brand' becomes 'mark' ('mark' can be a synonym of 'brand').
'accommodating' means one lot of letters goes inside another.
'everybody' becomes 'all' (I've seen this before).
'h'+'mark'='hmark'
'hmark' placed around 'all' is 'HALLMARK'.
'of' acts as a link.
(Other definitions for hallmark that I've seen before include "Goldsmith's stamp" , "Official stamp" , "Distinctive feature" , "Standard sign for silver" , "It indicates the standard of precious metals" .)
