This will be the first time I try to get Free Dining. I was curious to know how Disney handles the two separate releases of codes - first wave is for Disney Visa cardholders (Monday, 4/7 rumoured), second wave is for the public (Thursday, 4/10 rumoured). Do all the eligible rooms get booked/sold out asap by Disney Visa cardholders, or does Disney "hold back" eligible rooms for the general public? We are currently booked at WL and would prefer to not have to switch resorts, and I've heard it can be difficult to get Free Dining at WL. Again - all comments/questions are in the name of curiosity! 
Thanks for any information!
