Welcome in Waikiki (5)
I believe the answer is:
aloha
'welcome in waikiki' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aloha that I've seen before include "greeting in Oahu" , "Hawaiian farewell" , "Hawaiian "ciao"" , "A Hawaiian welcome" , "A Polynesian hello or goodbye" .)
