You genuinely don't understand how he could possibly fund his trip with bitcoins? Or are you exaggerating to make a point? I think it is conceivable that he could fund his trip by bartering for the majority of his food and/or lodging using bitcoins. That is, it is a possibility that there are people in the United States who will accept bitcoins in return for providing food and/or lodging. And presumably as a "digital currency guru" he would be able to identify those people and effect payment with the agreed upon medium. He even has a fallback option of cash if there is something he cannot acquire through the use of this bitcoins.
