if you are going to get a room, try the Sheraton Hotel. At the back of this hotel there is a parking lot, tell him to use this parking and wait. Now YOU, as an american can go and get a room at the reception. show youre passport and the nice receptionist will just simply say "Hows youre travel ma'am?". Youre blue passport is enough to tell them mind youre own business! Then call youre friend waiting at the parking lot, tell him youre room number and which floor you are.
