Rowdy hotel with broken loo again? Not ace (8)
I believe the answer is:
hooligan
'rowdy' is the definition.
(I know that rowdy can be written as hooligan)
'hotel with broken loo again? not ace' is the wordplay.
'hotel' becomes 'h' (phonetic alphabet).
'with' means one lot of letters go next to another.
'broken' is an anagram indicator.
'not' suggests deleting specific letters.
'ace' becomes 'a' (abbreviation).
'loo'+'again'='looagain'
'looagain' with 'a' taken away is 'loogain'.
'loogain' is an anagram of 'ooligan'.
'h'+'ooligan'='HOOLIGAN'
(Other definitions for hooligan that I've seen before include "Ruffian, yob" , "Destructive or badly-behaved youth" , "Young rough" , "Violent lout" , "Undesirable" .)
