Ford maybe parking next to hotel guest (9)
I believe the answer is:
president
'ford maybe' is the definition.
(US president Gerald Ford)
'parking next to hotel guest' is the wordplay.
'parking' becomes 'p' (abbreviation on road signs).
'next to' is a charade indicator (letters next to each other).
'hotel guest' becomes 'resident' (hotel resident).
'p'+'resident'='PRESIDENT'
(Other definitions for president that I've seen before include "Wilson once" , "top man" , "Country's leader" , "such as Bush" , "The elected head of a republic" .)
