I have been going to this Planet Fitness for a month or two. By far it is the biggest and nicest PF I have been too! There are a ton of machines and the only area that gets busy is weight lifting area. If you want to use machines though, you should have plenty of options.
I go at off times so the gym is pretty open. I tried going at 8pm on a Wednesday and the place was packed!! My girlfriend and I decided to go for a late night run instead.
The staff is friendly and pleasant but I never expect much as far as training or guidance from PF staff. It's just not PF's prerogative.
