Unfortunately, ESPN Club does not take PS's. Going in the summer, you should be okay, other than baseball there isn't too much going on in the sports world (unless this is during the Olympics, does anyone know when they start?). Go for lunch, from my experience the crowds are lower then. Also, go hungry, the portions are HUGE, I got a chicken sandwich the last time and it was 2 chicken breast on a bun.
Have a great time! We honeymooned at WDW too, it was fantastic!!
