Yes, sometimes they have promos. Also if you have more then 1 person to join in is cheaper!.
It depends on when you sign up. Sometime they have promotion that waive your sign up fee, so you just need to pay monthly. Check with them in person and negotiate to include multiple clubs entry or kid clubs (so you can drop off your child while working out) without extra fee
I don't know, i just work out at gym
