This is specific to the 7th Ave and Camelback location. I was grandfathered in when LA Fitness bought out all the 24Hour Fitness locations. This is a good thing, since I pay hardly anything per year and now have more gym locations to attend.
The location is rather busy in the afternoon! However, in the early morning, it's rather easy to find a machine. I do not look forward to new year's resolution busy times.
Group ex classes: I've tried Tasha's cycle classes. These are tons of fun. Plus, the bikes have computers on them, so one can see his/her heart rate, RPMs, and wattage. I tried a yoga class but was not that impressed. The instructor did not walk around and help people in the poses.
The restroom is always clean, and there is ample space in the locker room. There is a sauna in the locker room as well.
I wouldn't say the employees are trying too hard to be friendly, really. They say hi and that's about it.
