We stayed at the Bellagio, where they have the Chihuly ceiling. It's pretty spectacular.
Las Vegas was fun, but it's not somewhere I'm dying to go back to. They allow smoking in the casino, and to get to your room, you have to walk through it. So I ended up smelling like smoke the whole time. Ick! Plus the room was allegedly non-smoking, but it still stunk. I did enjoy the shopping, and the food. We gambled a little bit - won $50 on the Patriots and then promptly lost it in the slot machines. I'm just not a Las Vegas kind of girl. It's up too late and too glitzy for me.
