Superb facilities! You feel like you're in another world when you step into the Aria spa.  I didn't have any experience in the Salon so this review is mainly for the spa. I was pondering just getting the $30 day access (since I was an Aria guest), but i splurged for a massage as well--a hot stone massage will run you about $180. For the day access, they'll give you a wristband so you can use the facilities till 8pm if you choose.\n\nThings I liked about the spa:\n-Sleek, minimalistic/modern facilities \n-Easy check-in\n-Professional and friendly staff that give you your space when you want it\n-lockers with codes you can setup yourself\n-spacious stalls in the restrooms and separate changing rooms/shower areas\n-complimentary sodas, juices, water, coffee, etc\n-Hot Stone Bed Room: this was different than i thought it would be. There are about 6 beds total in this room. The \"beds\" are actually just platforms with tiles that heat up when you lie on them. So you're essentially lying down on hard ground and using a bamboo mat as a pillow. Not as relaxing as I anticipated. \n-Himalayan Salt Room: room with walls made of sea salt--you sit in lounge chairs that resonate and vibrate to the music that's playing. Each lounge chair comes with it's own set of headphone so you can get really lost in the music. This room is purposefully cold, i didn't see a noticeable difference in my mood or health, but it was kind of neat to experience. \n-Eucalyptus Steam room: This was fabulous....and they pump so much steam into the room so you can't see 5 feet in front of you. And you leave feeling like you got rid of all the toxins in your system. (Unisex only)\n-Sauna Cedar room: I didn't get to try this one, but have heard good things. \n-Three different jacuzzis with varying temps outside the steam rooms. (Unisex only)\n-Plenty of lounge chairs \n-Separate co-ed area which i didn't try out
