We have always gone to WDW during the free dining promotion and it has worked out great. For our next trip (late Aug - early Sept) we would like to consider doing the deluxe dining plan during the free dining promotion. How does that work? Will I need to pay the difference of upgrading from the regular plan? How much would that be for 3 people per day? I've already started planning out our schedule and, quite frankly, I can't imagine how I did a plan before WITHOUT doing it with the deluxe plan in mind. If we go with the regular plan now, I feel like I'd be missing out!
