I have been a member for almost 2 years and never had a problem with finding a group x class to fit my schedule or experienced over crowding in the main area.
However, times have changed in the past 4 months. Zumba classes are becoming over-crowded. It is maxed out way over the building fire code and they don't enforce it. If you are in line early, it doesn't matter. You will get pushed back into the corner as people arrive late and crowd up the space. There are no ceiling fans and it gets hot and very humid and thick. They need to add more classes or enforce the "limited space" and do first come, first serve. I don't pay a membership to not be able to access all the features and not get an effective workout.
I left class early today because I had no where to move, I was bumping into people, couldn't see the instructor, and was feeling a heat stroke coming on, though I was properly hydrating myself. It was torture, not fun like it use to be. I wasn't even at the class that was at the busiest time of day!
The other day my friend had to leave because they were short staffed and the Kids Club was filled up. If it is during Zumba, you can guarantee it's going to be busy for kids too. They should have staffed the area properly.
I feel my money would be best suited at a private studio rather than a gym.
