Vdara is great.

If you haven’t spent much time in Vegas before, you can spend a lot of time just visiting all of the casinos to look around. They all are decorated in unique styles and themes. The first time I was in Vegas was for work, and DH and I were newly married and didn’t have much money, so we just wandered around the strip taking it all in. I think we gambled about $20 each.

ETA: I LOVE the Bellagio fountains. I have passed a lot of time just watching those.
