My wife and I attended this show during our stay in Vegas. I must say I was very eager to see the show due to the iconic status that these two have earned.
The venue was packed and the staff was very friendly, though the box office for the show was scheduled to open at 7:00pm and the attendants showed up 10min late, with no apology for the wait.
The show itself was somewhat entertaining with moments of comedy mixed in well with the magic, additionally they do a great job of involving the audience. I will say my biggest complaints were the seating and acoustics. We were seated in the mezzanine section and had a difficult time hearing. It was also difficult to see some of the magic due to the distance from the stage. I know some may think 'just buy better tickets' but just because you don't have the best seats doesn't mean you shouldn't be able to enjoy the show.
Lastly, the Rio does not really deserve to host this show. The hotel is underwhelming to say the least and is severely outdated.
In closing, it's definitely not a show that I would attend again.
