Guidance to find cheap accommodation (8)
I believe the answer is:
steerage
This clue is a double definition.
'guidance' is the first definition.
(thesaurus)
'cheap accommodation' is the second definition.
(I've seen this before)
'to find' is the link.
(Other definitions for steerage that I've seen before include "The cheapest fares" , "Cheap part of ship" , "avoided by the "posh" set" , "Cheapest part of passenger ship" , "cheap transport" .)
