Boynton Canyon Trolley Tour from Sedona, AZ

I very rarely take the time to write a review. But since it's really hot in Sedona, I don't want someone else to have this same experience. Saw the Red Rock Trolley co. logo our first night. Contacted to get two spots for a two hour tour because it was going to be too hot for us to walk around/hike - we wanted an air-conditioned tour van to see the sights. The AC was hit or miss, very uncomfortable. And the guide was more interested in talking about herself than telling us about the area. My spouse is rarely critical but labeled her "very uninformed". Maybe there's another van, maybe another guide, but be forewarned.
