Spa Mio is a nice little oasis in M Resort.  If you live near-or are staying at- the M Resort, then this is a decent spa day location.  If you're on the strip or in Summerlin, it's a bit of a trek.\n\nI spa frequently in Las Vegas, as well as when I travel.  Overall, the spa was very nice.  I was pleasantly surprised as I expected it to be over priced and not deliver - as it (to me) is a \"locals\" casino specializing more in bingo and buffets.  \n\nSpa attendants were friendly and always anticiapting needs- fully attentive to guests in a quiet, spa-like manner...not chatting amongst themselves.  Amenities were great- all Moroccan Oil shampoo/conditioner, plus shave cream, razors, etc- what you expect to find at high end resorts.\n\nThere are seperate men/women sides for sauna/jacuzzi, etc.  The dressing area, waiting area and jacuzzi area are fairly small, but it seems to work for their business level.\n\nMy girlfriend and I both had mediocre (at best) massages.  I'm guessing this is because it's hard to keep really good massueses if they aren't fully booked.  \n\nWe were interested in getting lunch.  The options were: Cafe, Buffet, or a limited option for \"in- spa.\"  We opted to head back to the strip...we're not reallly cafe/buffet girls...but good to know that if you're hungry, you can get more than an apple or babana in the spa.  Which- by the way- they had a variety of fruit in the fruit bowls; as well as a couple options for specialty beverages and bottled water.\n\nOverall pretty good experience, but I would most likely try out another spa that I haven't been to yet. But, if you're at M Resort- I would highly recommend it.
