There is no cooking in the rooms but there are microwaves and toasters in the food court. People heat up their leftovers all the time. I can't see how you would save any time trying to heat something in your room anyway. I've cooked eggs, bacon, chili, soup, popcorn, etc. in the foodcourt microwaves, and never had a problem. Just remember to try to clean up any spatters or messes you make.
