Tour Hoover Dam another way! Booked a Hoover Dam bus tour from Vegas with Grand Canyon Scenic Airlines, and came to realize they contract w Gray Line busses. Bus driver was a knowledgeable guide but annoying with unfunny jokes and constant chatter on the mic. Everyone had to wait for about an hour, after hotel pick-up, at the bus terminal at this location while two other busses arrived. Here they attempted upsell us to "deluxe" tours and helicopter rides about five times. Ultimately got back to Vegas 2-3 hours later than they'd said. Pros: Driver pointed out nice views along the way, drove the bus about five minutes out of its way to bring us past a herd of grazing bighorn sheep, and dropped off at almost any point along the Strip.
