I don't consider free dining "free dining" for a long time now. Rack rates are already stupid high with less and less perks. EMH used to be a major draw for us as 1 park had 2 or 3 extra hours. Now it's often less than 3 most often, and park hours in general are shorter. Free parking was also big, now that maybe a thing of the past. Finally rack rate used to be at least in the general ballpark of area hotels. Now rack rate is obscene.
The dining plan is a ripoff now anyways. Unless you really were going to eat enough to "spend" the alotted value per credit, you are tossing away money. Usually the hotel discounts beat FD vs paying OOP.
Don't forget to remember you are responsible for the tip even with the DP too.
