Where else in the world can you walk by an endless row of over-zealous porn slappers on the street one minute, then be sitting in an opulent theatre watching incredible performers the next?
This was my second time watching O, and it's definitely a different experience from the balcony point of view, versus the lower level. If there's a good compromise between getting a good view and saving a bit of money, try to get seats for the first row of the balcony section. Then take the money you just saved and head for the tables later.
I ordered the tickets online and got a dead-on center view of the theatre. If you're like me and are fascinated with how things work, it's just a marvel watching now that incredible water set changes throughout the show -- especially from an elevated perspective. Take a glimpse on the right in the glass window where they play the live music, and watch those ladies sing and groove to the upbeat music. You almost want to get up and dance along with them.
Mystere offers some of the similar "circus" acts, but on far less extravagent set and tickets are far less expensive. If you're looking for storylines and a dramatic theme, check out Le Reve or KA. Utilizing the water element beautifully throughout each performance, O is a great show to watch if you're new to the world of Cirque du Soleil.
