You can also get a grocery delivery, which would mean you could have refrigerated/perishables in your room, as well (fridges are standard at CBR). We made instant oatmeal using hot water from our room's coffee maker. In your room, you can also do cold cereal and milk, bagels and cream cheese/butter, yogurt and granola, etc. We also made sandwiches once or twice, stuff like turkey, bologna, cheese, etc.
Someone mentioned the walking distances to the food court, location of a microwave. Yes, please keep that in mind. If you use the microwave but then intend to take the hot food back to your room, it may not be hot when you get back. Even from my preferred location room at CBR last year (Trinidad North 3340), it was a good 5 minute walk to the food court. Plus, if you need to heat several portions, then the ones you heat first will be sitting out while you heat the others and then you'll have to walk back, etc.
