I'm booking a trip here soon. Staying at Aria this time for sure. Like the crowd there, and the shops, and the margaritas, and the corner suites!
My favorite steak joint is the Cut at Palazzo. I also love the Mexican spot on the canal at Venetian for Lunch. Inexpense, great setting, awesome food.
I love Ceasars for shopping around while I drink.
I usually like to check out a show. Zoomanity was pretty damn good. Little drink, little nakedness, but still classy and entertaining.
Monte Carlo has a sick pool area for day time fun.
There are some awesome zipline places just out of town than have pretty insane setups.
Helicopter rides? Rent a Lambo? :-)
