Bleh. I should have known better than to try a different hostel. I've had about two hours sleep because it's so hot in the room (the rest of the pace has nice AC, but the room is claustrophobic and stifling hot), and I got locked out of my room TWICE because the keycard stopped working. On top of that, mr_t00by went home a day early because of money. I should have gone with him, even if they were planning on driving straight through and/or sleeping in the car.
I've already paid for tonight here, but I don't care. If Clarence Castle doesn't have room for me to stay the next two nights, I'm going home.
ETA: Success! I got the last bed at Clarence Castle for tonight, and made a reservation for tomorrow as well. Also, used my not-here debit card to reserve a ticket to Second City for tonight, so I don't have to spend my cash on it.
