Vehicle parked outside hotel daily (4)
I believe the answer is:
char
'daily' is the definition.
(I've seen this before)
'vehicle parked outside hotel' is the wordplay.
'vehicle' becomes 'car' (car is a kind of vehicle**).
'parked outside' means one lot of letters goes inside another.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'car' placed around 'h' is 'CHAR'.
(Other definitions for char that I've seen before include "Make black by burning, say toast" , "Noiseless" , "Singe, scorch" , "Kind of small trout - burn it black" , "tea > daily" .)
