I believe the answer is:
tour
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">sightseeing trip</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for tour that I've seen before include "Extensive journey" , "Go on holiday or inspection journey" , "Rout (anag.)" , "Journey round" , "Trip visiting several places" .)
