Welcome to the DIS.
CBR is usually pretty good at granting room requests. But they are only requests so be prepared for that.
As far as food how long are you staying? We have done WDW very cheaply when we had a cooler in the room with lunch meat and milk. We did breakfast in the room and did sandwiches later in the day. We had one meal in the parks. It all depends on what your idea is concerning meals.
