Good gym, bad experience with their childcare
Facilities are nice and access to equipment isn't a fight. They do a good job of keeping things clean, as well. You can't stop gym-goers who don't clean up after themselves, so can't blame them for that.
For classes, they can be hard to schedule with. We've had the experience where "someone lost the paperwork" twice. We also had a bit of an issue where a discount given by the gym was reversed by billing and we had to resolve it.
Regarding the childcare services, it's scary. I left my daughter there once and came back to find her bawling in a corner with other kids throwing toys at each other. The distracted teenage girls "watching" things were blabbing about their life drama without paying attention. I asked them to handle the violent kids and they did, with apparently requisite eye-rolls characteristic of drama queens. Another gym-goer (a police officer) and his wife told me later that the gym childcare centers are unregulated by Arizona law. They found their kid wandering the hall once and no one could answer why or how. So, they don't take their kids their anymore. My wife and I followed their lead.
Really torn on the place with so many pros and cons, but it's close and ha lots of options...
