Hotel also known as a dance (4)
I believe the answer is:
haka
'a dance' is the definition.
(I've seen this before)
'hotel also known as' is the wordplay.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'also known as' becomes 'aka' ('a.k.a.' can be a synonym of 'also known as').
'h'+'aka'='HAKA'
(Other definitions for haka that I've seen before include "Maori ceremonial war dance" , "intimidatory chant" , "Maori war dance used by All Blacks" , "routine before start of match" , "Maori ceremonial war-dance" .)
