I would go down the middle on this one. Very light duty cooking... We rented a timeshare in VA last year, and were close enough to drive from home(if you are flying, this won't work), so here is what we did. I made lasagna, baked ziti, a turkey-veggie-noodle casserole thing, sloppy joe meat, and chili at home in either disposable baking dishes or, for the meat and chili, the ziploc twist top containers...wrapped everything super tight and froze it about a week ahead of time. Shoved it in a cooler the morning we left, and by the time we got there 4 hours later, it was still frozen! I packed cereal, and vacation treats (cookies, candy). Then when we got to VA, went to a supermarket and bought packaged salads, buns, lunchmeat, some small condiments, milk, juice, and bottled water.
We had cereal or toast in the morning before heading out, except for one or two mornings we felt like eating out. We ate lunch where ever we were, and usually by mid-afternoon, we wanted a break, so we would go back to the room, cool down, rest, and yes, I would take a container out of the fridge and pop it into either the microwave or the oven and push a button. That is how I cook on vacation. No work involved. When we couldn't eat off of paper plates the dishes just got thrown into the dishwasher, and we went back to the park after we ate. Now, would I prepare a whole meal from scratch in a timeshare??? On vacation??? No.
Oh, and laundry? I am one of the strange birds who loves to do laundry on vacation. Less to pack, less to carry, less clutter in the room. Normally, at the timeshare, I would start a load before we went back to the park in the evening, and dry it once we were back, so it never sat in the dryer. I did laundry at AKL also, that was mommy time with the animals and a Pina Colava though. I made it a point to do a lot of laundry there
