My wife and I have stayed at the Aria several times, but we have never utilized the spa services. We are staying at Mirage this trip, but we plan to check out the spa at Aria one day. My question is this: is there a separate gym inside the spa at Aria that you get access to with a day-pass, or is it the same gym that regular guests get to utilize as part of the resort fee (which is right outside the spa)? I am guessing there isn't a separate gym inside the spa, but who knows. Thanks in advance for your feedback!
