I've seen the show three times in Vegas and it is terrific. He plays a lot of his hits, some new songs, doesn’t take himself too seriously, and seems to be having a good time. Each show was quite different in song selection, with a few hits never changing. His voice is still solid and he connects well with audience.
Most questions I get about the show are in regard to seating. I've sat in the stage seats, second row center section on the aisle and front row on the right side of the stage.
At this point, they don't sell these tickets at a reduced price anywhere, so going direct through the Hilton is the best deal. If you call the hotel you can pick out your seats with some help from the operator. I like the aisle so I can drift a bit into it if a tall person sits in front of me. The stage seats were a bit of a disappointment. Though you are really close to him for a couple of songs, and you get all the free champagne you can swallow (that almost evened up the ticket prices in my case), he is in the center of the stage most of the time. The seats on the main floor were much better in my opinion.
If you don't have the need to get real close, you may want to try for front and center in the balcony. Those tickets are about half what they are on the main floor front sections, but for the finale where Barry is on a scaffold at balcony level, they are the best seats in the house. For the rest of the show, they are still a good view. The theater is not too big, it seats 1400, so there aren't any bad seats. I was front row main floor last time and made eye contact with someone diagonally across from me in the first row of the balcony and could read her expression, so they were not far away. I would take balcony over orchestra seating.
Another neat thing about the show is that you can take pictures. You can just about flash right in his face and he doesn't seem to mind. As long as you don't have some paparazzi style zoom lens, you can click away. I wish more performers would do that - the stage lighting is so blinding what's a couple extra watts?
