My wife and I took the tour on October 4th.
The sights were amazing and the shining star of the tour was Walter Dirden, our "transportation specialist". He really kept the tour light and fun, filling us in on places, history, and happenings of Vegas that we never would have heard of with a more conventional tour guide. He was friendly but firm when it took to getting people back on the bus at stops. I'd go watch a Paint-Drying tour if Walter was the guide!
The major downside (hence the 4 stars) of this tour is how long the pick-up and drop-off takes. We were picked up at 6am from the hotel but didn't actually start the tour until close to 8am because of pick-up, and drop-off was a pain because it was done in the tour bus (why not in the smaller shuttles like in the morning?) and in Friday rush hour, so the afterglow of a great tour is diminished by waiting in gridlock traffic as you bounce around 10+ hotels dropping people off (we were near the last to be dropped off since our hotel was off the strip). Also, sorry guys, but the coffee at the gathering point/tour departure lot is nasty. Bring your own!
Overall, would recommend, if only for WALTER! MORE WALTER!
