I'm admittedly a bit of a hotel snob. When it's a five star hotel, there are certain amenities that you get used to or expect, and while Bellagio certainly isn't the worst hotel I've stayed in, it's not the best.
Check-in was a bit of a wait, standing behind hordes of tourists, but the staff were pleasant enough. The foyer, with its grand Dale Chihuly installation, is admittedly rather lovely.
Our room was nice- spacious, clean, and well-equipped. Our view was of the pool and spa area, and on the 20th floor- we didn't hear a peep from any of our neighbours, which I appreciate. The bathroom, while spacious, had a shower that didn't drain well, and the shower head was small and needed a proper cleaning. I realise this is the most 'first world problem' thing I've probably ever said on Yelp, but the towels were incredibly rough and scratchy. The bed was large and a bit firm, but very comfortable.
The pool area was nice, but the temperature of the pool was borderline freezing- my companion didn't want to get in- I swam one lap in the large pool and got out shivering. I'm not certain if the pool is heated, but if it is, they need to heat it a bit more. Drinks by the pool, as expected were somewhat overpriced ($40+ for a Hendricks gin and tonic and a double rum and coke), but that's Vegas for you.
All in all, our stay was pleasant, but not enough for me to insist on staying again. Next time I'll probably check out Aria or the Mandarin Oriental for a bit more of an upscale experience.
