The spa and salon at Aria is incredible. I want to count the days until I can return to that state of pampered relaxation. While Las Vegas is known for it's amazing spas and you have dozens of luxury spas to choose from on the strip, the Aria stands out for a few different reasons. First, there are more options here for co-ed spaces. Most spas limit you to just one area that is co-ed, but the Aria provides several which makes this a perfect spa for couples. Second, the areas to relax go beyond the typical spa (sauna, steam room, hot tub - those are all staples) and provides a sea salt room and heated stone beds (ah! Can I please get this installed in my home?!) which just gives you more space to unwind and spread out among the other guests. The outdoor pool is also an awesome space and a great option for spa guests. The actual service (facial and pedicure) were both phenomenal and worth the price. The service provided by all I encountered was also excellent, helpful, and friendly.
The only downsides that come up is the outdoor pool space has really limited space for seating which quickly gets filled up and also the pool overlooks the Aria's other party pool which means that there is loud music in the afternoon and evening. It wasn't a big problem, just something to be aware of.
