The views are spectacular. For that reason alone I’d recommend booking a tour that includes the night segment. I should add, however, the tour guide we had was rather sub-par. The entire bus was rather disappointed with her lack of expertise. Often we would pass restaurants and she would read the advertised signs as content. We’d hoped for more novel content. In addition, I was under the impression that the tour was 3 hours. Our tour was only 2.25 hours. Finally, our bus had a covered top. We could not see out the top, only the sides.
