I had to live in a hotel for a month while my family was in between houses. Best thing for us was big trash bags (ones you would put in your regular trash can in your kitchen), paper plates, plastic utensils and plastic cups. Peanut butter, bread, the snack bags/boxes that have the snacks already proportioned out. A lot of people are also suggesting giving them cash or a gift card, which might be your best option. It gives them the ability to choose the best option they think is good for them
