After graduating on Friday, my SR was taken to O'Hare at 0100 (in the morning) on Saturday. Her flight didn't leave until 1250. So, there were a bunch of tired Sailors waiting for their flights. If you are able to do so, I recommend bringing pillows and blankets for sleeping. The USO does not have the room to support that many people all at once so, many ended up sleeping near the gate of their flights. Many of them were just plainly tired, along with family members.
