Transport rental including hotel transport (7)
I believe the answer is:
enthral
'transport' is the definition.
(synonyms)
'transport rental including hotel' is the wordplay.
'transport' is an anagram indicator (letters are transported elsewhere).
'including' indicates putting letters inside.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'rental' is an anagram of 'entral'.
'entral' going around 'h' is 'ENTHRAL'.
(Other definitions for enthral that I've seen before include "Hold spellbound" , "Beguile" , "be captivating?" , "yoke" , "Fascinate - grip" .)
