Outline of hotel suite changes (10)
I believe the answer is:
silhouette
'outline' is the definition.
(I know that silhouette is a type of outline)
'hotel suite changes' is the wordplay.
'changes' is an anagram indicator.
'hotel'+'suite'='hotelsuite'
'hotelsuite' with letters rearranged gives 'SILHOUETTE'.
'of' is the link.
(Other definitions for silhouette that I've seen before include "Shadowy outline" , "Outline representation" , "image" , "Outline figure" , "Profile of characters" .)
