What Serack is neglecting to mention is that he forgot to get a reservation anywhere. I let him use the second bed in my room (a double being cheaper than a single for some reason) and when I went to pay the extra $15-$20 nusiance charge, being a fine upstanding citizen (stop laughing!), the lady working the desk just stared at us with her mouth agape and said:
"Nobody's ever admitted to adding a person before. Let me get you an extra key. No charge."
So I gave her a beer as thanks.
