Back before I lived in Vegas, I had the awesome experience of staying in a suite here. It was epic and I dare not ask how much it was cost. (Thanks, old job.)
Now that I live here and many more newer casinos have sprung up, I do find the Bellagio to still be one of the nicest but in dire need of upgrading its air filtering system. The smoke is strong here and it's probably from the years of it accumulating in the carpet, furniture, etc.
I still enjoy coming here for the botanical gardens, the outside water show and the overall upscale feel. The glass art always takes my breath away and I love that the Bellagio Gallery of Fine Art has Locals Wednesday for only $10!
Also, Cirque du Soleil's O is my favorite show ever. The opulence this hotel has is really showcased through their theater.
Parking lot is a little small compared to a lot of other hotels, but again - this place was built a little earlier than others.
