I think that "too much food" is absolutely a valid statement, depending on your family. For us, it was
too much food. We did DDP (plus, not deluxe) and CL in July and we could not keep up with all the food!
We did not "hoarde" CL treats and bring them back to our room, but on the nights that we ate the evening apps, we were so stuffed that we couldn't possibly eat another meal. Plus, we wasted soooooo much food. Rarely do we ever get/eat dessert...we just don't. So to "have" to get it eat with lunch and dinner was kind of ridiculous...and no, there is no waiter sitting there forcing you to eat it, and we would often just decline but really...we were paying for a lot of food we didn't even eat. We left an 11 day trip with 12 unused quick service credits!
So, the "too much food" argument, for my family is about wastefulness, and paying for only what we "use". We used to love the DDP, so it's not our first rodeo...but for us, the CL provides the eating experience that my family is more used to. Our next trip, we are going to forego the DDP and just do CL instead.
