We have visited Vegas many times & stayed at quite a few of the big casino hotels along The Strip, but never in City Centre, so we thought we'd give it a go this time & we were tempted by the non-gaming, non-smoking features of Vdara.
We had a nice (but not luxurious) room with a good view, & overall didn't have anything to complain about, but we won't come back for the following reasons;
No atmosphere. Some may view the quietness as a positive, & it does make a nice change from the usual chaos of Vegas, but eventually we started to feel as if we were cut-off from the action.
Distance. Vdara is quite a trek from The Strip. Although we'd dropped by CC before, it isn't until you are staying towards the back of it that you realise how vast it is. It is also confusing at first to find your way. We are Vegas veterans & we got lost more than once.
Staff. No-one was unpleasant, but there is a general lack of enthusiasm about the place. The 2 of us arrived by cab with 4 large bags & no-one greeted us or offered to help.
Facilities. The pool is disappointing by Vegas standards. It is small, & the sunbeds are uncomfortable & wedged so close together. The downside of a view of the Bellagio pools is seeing how nice they are by comparison. There is only a tiny bar & no restaurant other than a small cafe & ferociously expensive store. We didn't use the spa or gym, so I can't comment about them. Wi-Fi was OK, but why-oh-why no in-room coffee facilities? (Apparently you can request them, but with no guarantee of succes judging by other reviews)
In summary, Vdara is a nice enough (business) hotel that would do the trick in most cities, but if you want a real (& convenient, albeit smoky) Vegas experience stick to one of the 5 star big guns on The Strip.
