Was oddly, surprisingly underwhelmed by the Bellagio spa.
Well, let me restate. Totally OVERwhelmed by the size of it; getting from the locker area to treatment rooms involved what seemed like a quarter-mile walk through an uber-contemporary series of hallways.
My body scrub and mini-facial was fine but--and this is due in part to my choice of services--I feel like I paid a heck of a lot to have someone rub some salt on me, for me to take my own shower to wash it off, then coat me in goo. And when I heard the telltale "beepbeepBEEP" of a Clarisonic face cleaner, I was like, "Seriously? I'm paying you to clean my face with the same exact gizmo I have sitting on my bathroom counter at home?!?"
I've been to a good number of spas and Bellagio's is certainly a great example of pampering but I would suggest that you select treatments that really require lots of service (massage, perhaps?) to get your money's worth.
The mani-pedi combo is nice, because they do them both at once. Saves time and makes you feel like a freakin' spoiled rotten princess/beyotch.
