Would it be worth renting a fridge for your stay? I know it's $10/day, but you can sure get a lot of things in that little fridge to save more than you pay for the fridge. You can even turn it up cold enough that it will act like a little freezer. Besides putting in water, you can (if you don't turn it up too cold) some fruit, cold meat, etc., and more than make up the difference by having a few picnic meals.
