I used a 16-35 for the entirety of my trip out west including Horseshoe Bend. 16 was almost not wide enough by itself for the Bend. A two-shot pano would do it, though, just a bit to the left and another a bit to the right. There is a spot directly in front as you walk down that has a good view without fences and such to impair a good shot. Sun sets directly in front of you most of the year so time it to suit what you want, if you go. Which I do, because it’s a fantastic view!

Same. I treat tag-along friends and parents etc. as unpaid help. They typically love being involved.
