Not impressed. We departed 25 minutes late, so don't plan a tight schedule for after the 90 minutes. Air conditioning appears to be inadequate. It's the Nevada desert for God's sake! Long line for the bar. Canned narration is hard to hear. They allow smoking, so the smokers smogging away up top were happy (Hack, hack! Cough, cough!) The only upside is you get to see Hoover Dam for about 10 minutes for photo ops. You could just drive a few minutes further and view Hoover Dam from a viewpoint off the road for free. Otherwise, Lake Mead is a rocky-rimmed wasteland with it's own special beauty that gets old after 10 minutes. It is what it is. The extra star is for the staff. All friendly and efficient. Oh, almost forgot. There is a $10 fee to get into the National Recreation Area. It is good for 7 days, but big woop if you are just coming for the cruise.
