See great changes in cheap accommodation (8)
I believe the answer is:
steerage
'cheap accommodation' is the definition.
(I've seen this before)
'see great changes' is the wordplay.
'changes' indicates an anagram.
'see'+'great'='seegreat'
'seegreat' is an anagram of 'STEERAGE'.
'in' is the link.
(Other definitions for steerage that I've seen before include "Cheapest part of liner" , "Cheapest accommodations on old passenger ships" , "It's the cheapest way to go by sea" , "main accommodation" , "Cheapest accommodation in old passenger ships" .)
