I love this gym. It is clean and offers towel service at no additional cost. They have a ton of class options for free and a fee. I read a post about the front end service and customer service being horrible, I completely disagree. I play games trying to sneak out with them not catching me to say have a nice day, rarely happens.
I observe the personal trainers and they always seem really nice. I often see their victims getting a great workout, I have to high five them sometimes.
My only complaint is no locations in Arcadia/Biltmore area, that would be great. I've been to four locations and I feel the same level of consistency and friendliness at each location. I frequent Scottsdale Pavillions the most. I wish they had a referral fee as I have brought a few friends to the gym.
The child service offerings are great for parents, coming from a person with no children. The date nights and many other offerings can really help a single parent get some things done and a married couple have a nice Friday night out.
Having worked out for 20+ years, I don't think you'll find a better valued gym.
