IDEA Personal Trainer or IDEA World Fitness Conference? Which one do you recommend attending

I am a Fitness Director at a JCC in Connecticut. I supervise a staff of personal trainers who work the fitness floor. I am also a personal trainer and group fitness instructor. I have been to Mania's and ECA several times, and am now looking to venture to an IDEA conference. I want to walk away with having hit workshops that tap into fitness center management as well as personal training and small group training. Mania's and ECA have a heavy focus on group ex, I would like a focus on a broader spectrum. Can you tell me what each conference is like?
