We didn't have time to shop and eat, went 6 hours with nothing to eat. Though we would stop at Lake Mead but only passed by for an over look. Got dehydrated and sick from drink facet water during the Dam Tour, when I got home I vomited and was laid up in bed for the rest of the day, all night, and all of the morning. Bus Drivers kept asking for tips, and though they were mostly nice, I felt rushed. Long story short we didn't tip, and won't go for the cheaper tours again. Pack a lunch, they wouldn't let us take our hydroflasks on the tour.
