Shrubbery or vehicles outside a hotel (6)
I believe the answer is:
bushes
'shrubbery' is the definition.
(I've seen this in another clue)
'vehicles outside a hotel' is the wordplay.
'vehicles' becomes 'buses' (bus is a kind of vehicle).
'outside' means one lot of letters goes inside another.
'a hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'buses' placed around 'h' is 'BUSHES'.
'or' acts as a link.
(Other definitions for bushes that I've seen before include "Low woody plants" , "Shrubs" .)
