I stayed here once before and remembered liking it. Wishing on this trip we'd tried something else. While staying at the Bellagio sounds like a great thing... it isn't. Sure, the lobby is beautiful and the garden is pretty... but you aren't staying in the lobby or the garden.
The rooms are just ok. Bathrooms are pretty awesome. Beds SUCK! i hardly slept the whole trip because the bed was so uncomfortable... made my back hurt. And what high-end hotel doesn't have down comforters?!?! are you kidding me?!?! ugh. Service was ok, but not great. We asked about late checkout and were told we'd have to call the day we were leaving to request it. So we did. "we don't do late checkout." what? you have to pay a half day charge and then you can stay until 6.
we were unimpressed enough with the room that when it was time to eat and gamble, we went elsewhere... i just wanted to get out of there.
non-smoking floors are not enforced at all as far as we could tell.
service was pretty good. the air was really bothering me, to a point my sinuses were hurting. we called and asked about a humidifier, which they gladly brought up. that was nice.
overall - we won't be back.
