My poor exploited twins have cooked their own meals for about 4 years entirely alone as I don't cook for them (although they have gone for half board halls so will probably do much less cooking than now once away).
With my older children we just had two of us in the front seat and all the back and boot for stuff so it fitted in. With the twins I am going to take one car load and one of them will drive the other car with more stuff and then although it's not advised they will be keep one car there.
I don't think there are many cooking facilities at their halls - just a microwave and fridge.
