Luxurious hotel not appearing to give credit (4)
I believe the answer is:
plus
'credit' is the definition.
(I've seen this before)
'luxurious hotel not appearing' is the wordplay.
'luxurious' becomes 'plush' (I've seen this before).
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'not appearing' indicates named letters should be taken away.
'plush' with 'h' removed is 'PLUS'.
'to give' is the link.
(Other definitions for plus that I've seen before include "To the French it's more" , "Advantage; also" , "advantageous" , "credit" , "Add" .)
