Sightseer (7)
I believe the answer is:
tourist
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">sightseer</span>' is the definition.<br/ ><span class="explanation-format__explanation">(someone visiting certain sights)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for tourist that I've seen before include "One travels for pleasure" , "Holiday traveller" , "Visiting sightseer" , "Tripper, sightseer" , "Cheap travel class" .)
