For every trip we prep, my wife and I try to figure out ways to save money. And I always remind her we have a full kitchen and can cook meals. And she always looks at me like I have three heads.
We've used the refrigerator to store leftovers. We used the dishwasher extensively when the ids still used bottles. We've used the plates to eat like human beings with dignity on the occasions I went to get stuff from the food court to eat in the room. That's it.
The main reason we get the 1BR is so we can have privacy from the kids and for the washer/dryer so we can keep doing laundry, pack less but not spend a whole chunk of the trip in the laundromat. And we always try to get BLT or AKV for the extra bathroom. If DVC ever made a unit with all of those amenities but just a kitchenette, we'd use it.
While I understand and appreciate where your wife is coming from, I look at the fully equipped kitchen and think "Why am I eating out when I've got a kitchen and I can cook!"
Yeah, I'm crazy....
