Booked a Zion tour with this outfit.
Although the tour was good and my fiance enjoyed talking photography shop with the guide, honestly Zion doesn't need a guide. They shuttle you from Vegas to the gates of Zion and set you free because the park doesn't allow for outside guides. Why then are you paying a guide to drive you out? Got me... yeah there is some bits of info and such, but not really enough to make it worth it to me.
For $200 pp and 2 of us ($400), we honestly should have just rented a car but I didn't know and thought something would be added to experience. Sadly it wasn't a good bet.
They have lots of other tours and maybe it's a bit different but Zion is a pointless tour experience but still a beautiful place still worth visiting!
Something I really disliked about this tour was the breakfast stop at McDonalds... only slightly classier than stopping at a casino dumpster hoping to find buffet leftovers or something. If I had known this I would have packed a breakfast with me.
