Short form: If you even think you might want or need a great massage, and you are in Las Vegas, GO MAKE AN APPOINTMENT WITH ARIANA, NOW.
TL;dr
I was in Las Vegas for business (a certification test and tech conference), after a week of helping my parents, and it had been a very long time since I had a massage. Too long. Wayyyyyy too long. A friend in Portland recommended Ariana, and she was able to fit me in. Not only was it a freakin' AWSOME massage (pressure just right, clever massage table that was microadjustable so my normally over-tight self was actually comfy face-down, felt much better and was demonstrably more flexible after)...but she was personable, and made the two hours one of the best things I could do while traveling for stressful events.
