Trip Advisor includes enthusiastic review of girl in temporary accommodation (6,5)
I believe the answer is:
travel agent
'trip advisor' is the definition.
'enthusiastic review of girl in temporary accommodation' is the wordplay.
'enthusiastic' becomes 'rave' (as in rave reviews).
'review of' is a reversal indicator.
'girl' becomes 'gal' (synonyms).
'in' means one lot of letters goes inside another.
'temporary accommodation' becomes 'tent' (I've seen this before).
'gal' reversed gives 'lag'.
'rave'+'lag'='ravelag'
'ravelag' inserted within 'tent' is 'TRAVEL AGENT'.
'includes' is the link.
(Other definitions for travel agent that I've seen before include "Arranger of trips" , "Trip organiser" , "Holiday seller" , "Dealer in air tickets, package holidays etc" , "One arranging holidays" .)
