I get tired of eating restaurant food every day, especially Disney food. We loved having a kitchen last week. I don't like to cook all that much even at home, but it does not bother me at all to make a simple dinner or two on vacation. We are either back from the parks by dinner time, or we take a mid day break and return to the parks after dinner. Lunch we usually eat at the parks.
One helpful thing I did was order groceries for the week from Garden Grocer...so worth the extra expense to avoid grocery shopping upon arrival. We drove so I brought some non-perishables and mostly ordered the refrigerated items we needed. One night I cooked chili - simple recipe - and we had leftovers on another night, and one night we ordered pizza and salad from Giordano's and had some leftovers for lunch the next day. We almost always eat a quick breakfast (bagels, yogurt) in our room before heading to the parks. We did eat out a lot of meals but it was really nice having some non-Disney food throughout the week. Saving money is an added bonus, but the main reason is because while I love Disney I can only handle so much of their food in a week.
