Just got back from a 4 day stay at the Vdara. Booked a Vdara Suite, used the $20 sandwich when checking in and got upgraded to a bigger Vdara City Corner Suite on a higher floor.
The room was very spacious and plush. It had it's own kitchen and two bathrooms and a washer dryer in suite, perfect for a long stay. The room was very quiet as you cannot hear your neighbor like a lot of other hotels. Housekeeping was prompt.
Pool was nice but fyi they close the pool bar an hour before the pool closes. The gym here is nice but a bit cramped but who goes to Vegas to work out.
Wifi was pretty strong, and my At&t 4G LTE was super fast here also.
Valet only but the were pretty quick, there's a air conditioned waiting room right by the valet window if the Vegas heat is getting to you.
Close to all of city center Aria/ Cosmo/ ect... and connected to the Bellagio.
I would suggest this hotel for anyone who wants to experience Vegas but be able to retreat to a nice quiet place and recover.
