Not sure what your expectations are, but this is a gym. I go to workout so I'm not really concerned with how nice the staff is. Having said that I don't remember anyone being rude to me.
Yes from 5-6:30 the gym is pack, not sure what you're expecting. I'm not paying for Lifetime Fitness. The gym was remodeled in 2010 and there are definitely enough machines to keep waiting down to a minimum.
The classes are pretty good, but sometimes hit or miss. They don't cost extra so it's not a big deal.
As far as LA Fitness locations go this is my favorite. Better than Dobson/Warner
Priest/Elliott
University/Rural
I have paid for a trainer here, they are pretty good, but overall could be better. These trainers are understandably geared toward people who need help/motivation not people who really want to get in top notch shape.
