I would say you should get center seats around the 5th or 6th row back from the front. The first couple rows are called poncho rows, which means you may get splashed by "flying paint" and other fun stuff, so you may want to avoid them if that is not your cup of tea.
This is a big show with lots to see from all directions. While most of the action is center stage, a lot happens above on video monitors and high up on stage which are cleverly integrated into the show. If you are too close, you will be turning your head too much to catch all the action.
Also, in case people don't know, Blueman Group recently moved from the
Luxor and is now playing at
Venetian.
