I am not given to superlatives, but \""O\"" is easily the best show in Las Vegas, and possibly the best in the world.  But if you take my word for it and go with expectations of the unbelievable, you may be disappointed.  And you may resent the substantial amount of dough you plunked down for tickets.\n\nOn the other hand, if you go without SPECIFIC expectations and just let the experience wash over you, not trying to follow the story line -- which doesn't exist in any case -- you most likely will leave with a grin on your face, a smile in your heart, and a five star review forming in your head.  It's happened to me four times over the years.\n\nHere are a few hints --\n\nTHE DOS:\n1.  The best seats are around the tenth to fifteen rows (row one is indeed \""A\"" here), and not towards the sides.  The main theater consists of sections 101 - 105, with 103 being the center.  102 and 104 are also fine.  Order way ahead - O often sells out.\n2.  I like the 10:00 time better because this is a stream-of-conciousness type of show and a couple of drinks (just a couple) frees the mind.  You can buy them just outside the theater and carry them in if you want.\n3.  Experience the theater itself - it is a wonder.  \""O\"" could not be performed effectively without this super-venue.\n\nTHE DON'TS:\n1.  Don't worry about the two clown routines, which are somewhat sophomoric.  They are needed to provide rest for the cast and a chance to change scenes.  You'll see why the rest is needed.\n2.  Don't focus entirely on the main performers.  Each scene has a focal point, but there will also be other things happening all over the stage.  These are an important part of the whole, so let your eyes take in the entire flow of the action.\n3.  Don't try to understand the lyrics -- consider it an sort of extra-galactic opera.\n\nBy the way, \""O\"" is a Cirque de Soliel show, of which there are five or six running in Las Vegas.  There is a simple way of determining which are the best: the shorter the name, the better the show.  \""O\"" is #1, followed by \""Ka\"", \""Love\"", etc.  Forget about Zumanity.\n\nAnd guys, if you are taking a date, \""O\"" in Las Vegas is as near a sure thing as there is.
