Must see attractions in Vegas for first timers?

[Big TR]

1. Shell out the dough to see Mystere. It's the best $180 my wife and I spent while in Vegas.
2. We went on a trail ride through the red rock canyons. It lasted about 2 1/2 hours. This was also really cool.
3. Bellagio buffet for lunch is where to go. Don't go to the Stratosphere for dinner. The food is mediocre and overpriced, just get a drink at the bar and skip the meal.
