I will be at my hospital too for a few days. I did it last year for Matthew as well. I brought a blow up mattress, sheets, a blanket, two pillows. Ear plugs, sleeping pills, eye mask (I sleep days). Flip flops for the shower and two of my own towels. A jacket, one outfit, pajamas and slippers. Scrubs for each day plus one extra just in case we stay longer. Snacks, a book, phone charger. Toiletries, Advil. And the things you normally take for your shift. My hospital pays double time for the whole 24 hours, so we don't have any problem getting staff.
