<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">sightseeing traveller</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for tourist that I've seen before include "someone on holiday" , "Sightseeing traveller" , "Tripper, sightseer" , "One travels for pleasure" , "Holiday traveller" .)
