This tour is a LOT of driving. The van is equipped with a TV which the driver plays informative videos, as well as mainstream feature movies to pass the time. It works alright.
The first stop, at the Hoover Dam, was the only part of the trip I didn't enjoy. Busses aren't able to park anywhere near the Dam itself, so you end up being really far away and the photo op really isn't that great. You don't get to stop at the visitor centre at all, which is a shame. You also never see the classic view of the Hoover Dam - as it can only be seen from the new bridge. There's not a lot of time for the Hoover Dam on this trip, and if it's a priority for you to see, I would recommend you take a dedicated Hoover Dam trip by itself.
Our next stop was in Kingman Arizona, at an historic locomotive and along Route 66. A nice photo op.
But, save the best for last - the Grand Canyon was spectacular. We arrived a little early which gave us just over 2 hours on the south rim. A nice leisure 4km walk on a paved path meant that everyone in the group could do the trek. It's quite safe and very easy. This gave us lots of time for good conversation, to take group/individual photos of the canyon, and to stop at the "Hopi House", gift shops, and have a drink before re-boarding the bus for the return to Vegas.
This trip is long, and with all the driving distances, can be exhausting. The driver provides breakfast, lunch, and water along the way, so you never feel hungry or dehydrated.
The driver (whose name I forget) was excellent. Very safe driving. Had lots of interesting tidbits to say about the area. He told us lots of tidbits about locals, interesting geography and geology, and would even offer to take a photo of our group. Very helpful.
One of the visitors on our trip came in a wheelchair - which, given the steps into/out of the bus, as well as a lot of walking on the trip, is not recommended.
