This is a great venue. Not too big and not too small. We saw Puple Reign at their new home in the Shimmer Cabaret. The show was excellent, as usual. The Royal VIP tickets for the show I saw are located in an orchestra style pit at the foot of the stage. The location of these seats seem like you'd be put in a position to look up, just a little too much.
The Regular VIP tickets (at $69 each from online purchase) place you at a position above the "pit people" and at the same level as the stage. For me, these tickets were the best for seeing the show (an less expensive). There is a bar inside and if you need to use a restroom, you have to trek across the casino for aways.
