One booked into hotel has seen dirt all over the place (8)

Ross

I believe the answer is:

resident

'one booked into hotel' is the definition.
(someone residing in a hotel)

'seen dirt all over the place' is the wordplay.
'all over the place' indicates an anagram.
'seen'+'dirt'='seendirt'
'seendirt' with letters rearranged gives 'RESIDENT'.

'has' is the link.

(Other definitions for resident that I've seen before include "Liver" , "Person living in" , "Someone with a home" , "Lodger" , "Dwelling in a place for some time" .)

I've seen this clue in The Guardian.
