As a mad statistician, I visit Las Vegas once a year, and I run a lot of crazy calculations. Here's some info you might find useful...
At the Mandalay Bay 10 AM daily tournament, The average player will last about 1.5 hours. With the $40 buy-in, this works out to $26.67 an hour to play (and lose). If you (or your bride to be) aren't very good, this is the best value on the south strip.
If you care to venture downtown, The Plaza has the cheapest "$ per hour" games (as low as $16.67). The quality of the room isn't so nice, but that's subjective. I'm all about the numbers.
Now, it you plan on winning with less skill, the Luxor daily tournaments will level the playing field. Their blind structure to starting chip count ratio is the lowest in Las Vegas. This means that luck plays a predominant role. Since Luck plays such a strong factor, local card sharks steer clear.
Without getting into the formula, and at the risk of throwing out numbers that mean nothing to you, Luxor's daily blind structure to starting chip count ratio is a 30. In comparison, Mandalay Bay is a 45, requiring slightly more skill, but still a lot of luck. Compare that to Caesars (7PM) or Aria (1PM) that have a blind structure to starting chip count ratio of 120, where the blinds slowly increase. This attracts some of the area's best players, since skill - not luck is king.
(Not to slight the Bellagio, I just haven't played there yet.)
