I am a professional tour director and guide, and accompanied guests of mine during our visit on Saturday, August 13. Staff was efficient, courteous, and professional. They explained things well to participants, and used humor effectively to lessen the anxiety of some. One course guides answered questions, maintained safety protocols, and moved through the 4 lines we did at a comfortable pace. This was one of several courses I've done privately or with guests in Colorado, and liked how the course was designed.
